For Wholesale Partners: The Professional Finish with Engineered Corner Systems

A great stone installation is defined by its details. Explore our factory-made corner pieces, proven to reduce on-site labor costs by up to 50%, and deliver the seamless, durable finish your high-end clients demand.

The Difference Between a Good Job and a Profitable Business

For professional contractors and distributors, the quality of the finish directly impacts your bottom line and reputation. Here are the core business advantages of making our factory-made corner systems a standard in your inventory.

Achieve an Authentic Look:

Our factory-made systems replicate traditional, full-depth masonry, providing an authentic character mitered edges cannot match. This is a key selling point for high-end clients that justifies a premium price.

Increase Installation Speed:

Pre-fabricated corners eliminate the most time-consuming part of the job. This allows contractors to complete projects up to 50% faster, increasing their profitability and enabling them to take on more work—driving more sales volume for you.

Ensure Lasting Durability:

Corners are the most vulnerable part of a wall. Our robust, single-piece systems create a reinforced edge highly resistant to impacts, preventing chips and eliminating costly client callbacks.

Reduce Project Risk & Waste:

Our engineered system minimizes material waste from mis-cuts, reducing scrap rates from a typical 15% down to under 3%. This provides a predictable, profitable, and professional outcome for your clients.

Global Distributors Share Their Success

Our reputation is built on the success of our partners. See why professionals in North America, Europe, and Australia trust our Stacked Stone Panels for their most important projects

"Renovation projects are full of surprises, especially old walls that aren't square. The Flexible Two-Piece corner system was a lifesaver on our last luxury remodel. We were able to create perfect, custom angles for a bay window that would have been a nightmare to miter. My crew saved at least 10 hours of complex cutting, which went straight to our profit margin. It's the ultimate problem-solver."

"For us, landed cost and inventory management are everything. Switching to Top Source Stone's Two-Piece corner system was a strategic masterstroke. Because they ship flat, we can fit nearly three times the quantity in a container, drastically lowering our freight costs. More importantly, their batch-matching is flawless. We never have to worry about sending mismatched corners and panels to a job site. Our clients trust us for it."

"On our high-end coastal homes, the details define the project. We specify Top Source Stone's Solid L-Shape corners because there is simply no substitute for the authentic, monolithic look of a solid stone corner. There are no seams, no compromises. It communicates a level of quality and craftsmanship that our clients expect. The finish is flawless and robust enough to stand up to the harsh coastal environment."

Engineered for a Perfect Finish & Rapid Installation

Our corner and accessory system is not an afterthought; it’s an integral part of a complete solution. Each component is engineered with the same precision and quality as our main panels to save contractors time, eliminate on-site risks, and ensure a flawless, professional result that stands the test of time.

Robust L-Shape Construction

Each corner arrives as a solid, factory-bonded L-shaped unit. This single-piece design provides superior strength and structural integrity compared to a fragile, on-site glued miter joint, ensuring a durable finish that resists impacts.

Guaranteed Batch & Color Match

We eliminate the risk of mismatched colors. Our corners are manufactured from the exact same quarry batches as your flat panel order, guaranteeing a seamless and consistent color, texture, and thickness for a truly monolithic look.

Precision-Cut 90° Angle

Using advanced, factory-calibrated saws, we cut and bond each corner to a perfect 90-degree angle. This manufacturing precision is impossible to replicate on-site and is the key to achieving the sharp, clean lines demanded by high-end architectural design.

Engineered for Rapid Installation

Our corner system is designed to dramatically reduce labor time. By eliminating the need for slow and wasteful miter cutting, contractors can install corners up to 50% faster, increasing project profitability and keeping timelines on track.

Superior Impact Resistance

Corners are high-traffic, high-impact areas. Our full-depth, solid stone construction is inherently strong and durable. It resists the chipping and damage that commonly plague thin, mitered edges, preventing costly callbacks and ensuring long-term client satisfaction.

A Complete Finishing System

Beyond corners, we offer a full range of matching accessories, including wall caps, sills, and trim. This allows you to provide a complete, cohesive, and fully integrated solution, positioning you as a one-stop-shop for your professional clients.

The Corner Installation Process Overview

Step 1: Surface Preparation

We provide professional guidance on preparing the substrate. Ensure the corner is plumb, structurally sound, and has the necessary barriers and lath applied for a secure, durable base.

Step 2: Plan the Corner Layout

Before applying mortar, dry-fit the first few corner pieces. Plan to alternate the long and short ends of the L-shape as you stack them up the wall to create a traditional, interlocking masonry pattern.

Step 3: Mortar Application

Our technical guides specify the correct polymer-modified mortar. Apply a consistent 1/2-inch (13mm) layer to the entire back of the corner piece (“back-buttering”) for maximum adhesion.

Step 4: Setting the Corner Piece

Starting from the bottom, press the corner piece firmly onto the wall with a slight wiggling motion to set it into the mortar. Use a level to ensure it is perfectly aligned before proceeding.

Step 5: Integrate with Flat Panels

Once the corner is set, install the adjacent flat panels, fitting them snugly against the edge of the corner piece to create a tight, seamless joint. Continue this integrated process up the wall.

A Technical Comparison of Our Two Corner Systems

We provide two distinct corner solutions to meet the strategic needs of our B2B partners. This objective analysis breaks down the key differences in their construction, application, and logistical advantages to help you make the most profitable decision for your business.

Visual / Construction

The Flexible Two-Piece System (For Ultimate Versatility & Shipping Efficiency)

This highly versatile system consists of two separate, flat stone components shipped without a pre-set angle. This empowers the installer to cut and join them on-site to perfectly fit any corner angle, whether it’s a standard 90°, an acute angle, or a wide 135° obtuse angle.

The Solid L-Shape Corner (For Guaranteed 90° Perfection & On-site Speed)

This is a premium, single-piece solution precision-cut from a solid block of stone to a perfect, fixed 90-degree angle. It arrives at the job site as a robust, ready-to-install unit, representing the highest standard in guaranteed quality for standard corners.

Core B2B Advantage

📐 Ultimate Design Flexibility Its #1 advantage. This is a universal corner solution for complex architecture, bay windows, and renovation projects where wall angles are not perfectly square.

📦 Maximum Shipping & Logistics Efficiency Shipping flat components allows you to pack up to 3x more linear feet of corners per crate, dramatically reducing your per-unit freight costs.

💰 Lower Upfront Product Cost The efficient manufacturing and packing process results in a lower ex-factory price, enabling more competitive pricing or higher margins.

⏱️ Maximum On-Site Efficiency For standard 90° walls, this product is unbeatable for speed. It is ready to install out of the box, completely eliminating on-site cutting and assembly.

✓ Guaranteed 90° Quality & Zero On-Site Risk The corner’s perfect 90° angle and durability are 100% factory-guaranteed, eliminating the risk of assembly errors and costly callbacks.

✨ Unmatched Authenticity & Perceived Value The seamless, monolithic appearance is identical to traditional solid stone masonry, commanding a premium price for projects demanding the best.

Angle Flexibility

Exceptional. This is a universal solution. The pieces can be cut and joined to fit any angle (e.g., 80°, 90°, 135°), making it perfect for complex architecture and renovations.

Limited. This system is specifically engineered for perfect 90-degree corners only. It cannot be adjusted for other angles.

Installation Process

Requires on-site assembly. The process involves measuring, cutting the angles, and bonding the two pieces together on the job site before installation on the wall. Requires higher installer skill.

Ready to install. The process is simple: apply mortar and place the finished corner onto the wall. Requires minimal specialized skill for placement.

Shipping & Logistics

Highest Efficiency. Shipping flat components allows you to fit up to 3x more linear feet per crate, offering the best possible value for international freight.

Standard Efficiency. The pre-formed L-shape is bulkier and heavier, resulting in higher shipping costs per linear foot compared to the two-piece system.

Ideal Project Type

The Problem Solver. Perfect for renovation projects with unpredictable angles, modern complex architecture, and for distributors who want a single, universal stock item.

The Speed Setter. The definitive choice for new constructions with standard 90° walls, large-scale commercial projects, and any job where on-site speed is the top priority.

The Precision Process Behind Every Perfect Corner

We control the entire process to ensure you receive corner systems and accessories that are not only beautiful but also precisely engineered for a flawless, modern installation. This is the source of your quality guarantee.

Premium Raw Material Selection & Matching

Every great corner starts with the right material. For every order, we select raw material blocks from the exact same quarry batch as the corresponding flat panels. Our geologists inspect the raw material to ensure it has the ideal geological integrity and color consistency. This meticulous matching process is our guarantee that your corner pieces will blend seamlessly with your wall.

Precision Cutting & Fabrication

This is where engineering meets craftsmanship. We use advanced, computer-guided infrared saws to make the initial cuts for our corner pieces, ensuring perfect 90-degree angles and dimensional accuracy. For our two-piece interlocking corners, each half is precisely fabricated to ensure a perfect, tight fit when installed.

Rigorous Quality Control

Before packaging, every single corner piece undergoes a multi-point quality control inspection. Our dedicated QC team uses calipers and squares to check for dimensional accuracy, angle precision, and any surface imperfections. This ensures that the corner systems that leave our factory are ready for a professional, high-quality installation, protecting your reputation.

Secure & Specialized Packaging

Corner pieces are high-value and have critical edges that need protection. We package them in their own dedicated, heavy-duty cardboard boxes with custom foam inserts to prevent any chipping or damage during transit. These boxes are clearly labeled and then securely packed within the main, robust wooden crates along with your flat panels.

The Sustainable Choice for a Smarter, More Durable Installation

Using our factory-made corner systems is not just a better building practice; it’s a more sustainable one. Discover how our engineered approach reduces waste and contributes to a longer-lasting, lower-impact result.

Significant Reduction in Material Waste

On-site miter cutting of panels to create corners is an inefficient process that results in a high percentage of off-cuts and chipped, unusable pieces. Our factory-made corner systems are engineered for a perfect fit, dramatically reducing on-site material waste. This responsible use of a natural resource is a cornerstone of sustainable building, minimizing what goes to the landfill.

Enhanced Durability for a Longer Lifespan

A project’s sustainability is directly tied to its longevity. A thin, mitered corner is a weak point prone to chipping and failure, which can lead to costly repairs and replacements. Our solid, full-depth corner systems create a robust and durable edge that is highly resistant to impacts. This ensures the entire stone facade lasts longer, reducing the need for future resource consumption.

A System Approach to Quality

Sustainability is also about quality and doing the job right the first time. By providing a complete, integrated system of panels and matching corners, we eliminate guesswork and reduce the likelihood of installation errors. This commitment to a quality system ensures a lasting result that performs as intended, which is the most fundamental principle of sustainable design.

Your Technical & Design Questions, Answered

Get clear, direct answers to the most common questions our global distributor and wholesale partners ask about our quality, logistics, pricing, and partnership program.

How do you ensure the corners and panels have a perfect color and texture match, especially for large or phased orders?

This is the cornerstone of our quality promise. We solve this critical issue through a strict Batch-Coding System. When you place an order for a complete system (panels and corners), we manufacture all components from the exact same blocks of raw stone quarried at the same time. Each crate is coded to its specific batch. For large, phased projects, we reserve the required quantity of raw material from that single batch to guarantee absolute consistency for all subsequent shipments.

What is your production capacity and typical lead time for a container order to major markets like the USA or Europe?

As a direct manufacturer, we have significant capacity. Our typical production lead time for a standard container order is 2-4 weeks. Ocean freight to major ports in North America and Western Europe is generally 4-5 weeks. When you place an order, we provide a detailed production and shipping schedule, and our dedicated logistics team manages the entire process, providing you with tracking and documentation for a seamless import experience.

How does your factory-direct pricing help us compete against local brands or other importers?

Our factory-direct model is your key competitive advantage. By eliminating all middlemen (trading companies, agents), you get the lowest possible ex-factory price. This provides you with a superior landed cost and a significantly healthier profit margin. It allows you to either compete more aggressively on price in your local market or reinvest the higher margin into marketing and sales to grow your brand.

What is your process for creating custom or private-label (OEM) products for our brand?

We are a true manufacturing partner. Our OEM process is straightforward:

Consultation: We discuss your requirements for custom sizes, angles, or packaging.
Sampling: We produce a sample for your approval, typically within 7-10 days.
Production: Upon approval, we manufacture the products to your exact specifications.
Branded Packaging: We ship the products in high-quality, custom-printed boxes featuring your logo and information, protecting your brand and market share. A Minimum Order Quantity (MOQ) applies for OEM services.

How do you handle issues if they arise, such as shipping damage or a quality discrepancy?

Transparency and partnership are key. While our secure packaging keeps our damage rate below 1%, we have a clear process for any issues. Simply document the problem with photos upon receiving the container and notify your dedicated account manager within 7 days. We will promptly issue a credit on your next order or, for significant issues, ship free-of-charge replacements in your next container.

What kind of technical and marketing support do you provide to your distributor partners?

Our goal is to help you sell. We provide a comprehensive support package, including:

High-Resolution Media: Professional project photos, videos, and product shots for your website and marketing materials.
Technical Documents: Detailed PDF spec sheets, installation guides, and testing data that you can re-brand.
Sales Training: We can provide remote training for your sales team on our products’ key features and selling points.

What is the strategic difference between the "Flexible Two-Piece System" and the "Solid L-Shape Corner"?

The choice is a strategic one based on your target market. The Flexible Two-Piece System is the ultimate choice for logistics efficiency and cost-effectiveness, as its shipping density is unmatched, giving you the best possible landed cost. The Solid L-Shape Corner is the premium choice for on-site installation speed and guaranteed 90° perfection, ideal for high-end markets where labor is expensive and quality must be flawless. We can help you analyze your market to determine the most profitable inventory mix.

What are your typical payment terms for new wholesale partners?

Our standard term for new partners is a 30% deposit to schedule production and the 70% balance payable upon presentation of the Bill of Lading (B/L) copy, just before the shipment arrives at your port. We are open to discussing more flexible terms like L/C (Letter of Credit) for long-term partners with established order volumes.
