Up And Down Cladding System Bracket Manufacturers

How Our Up and Down Brackets Work

Each bracket has an upper arm that supports the slab above and a lower arm that restrains the slab below. The kerf (slit) in the stone edge receives the bracket tongue, creating a positive mechanical connection. Shims between the bracket and the wall allow precise adjustment of the projection, accommodating building tolerances.

This dual function – load bearing and restraint – makes the system ideal for ventilated facades where panels must resist wind load and thermal movement without transferring stress to the stone.

Applications and Material Fit

Our brackets are used in natural stone cladding systems for commercial towers, institutional buildings, and high-end residential projects. They suit granite, marble, limestone, and engineered stone panels with kerf cuts. The stainless steel construction ensures corrosion resistance in coastal and polluted environments, and the material grade can be matched to the project's environmental class.

Engineering Value and Customization

We are not just a component supplier; we provide engineering support to ensure the bracket geometry matches your panel dimensions and structural loads. Our in-house mold and tooling team can produce custom shapes, sizes, and hole patterns. We also offer laser cutting and CNC machining for precise tolerances.

For projects requiring non-standard projection or higher load capacity, we can adjust the bracket thickness, width, and arm length. We work from your drawings or samples to develop a bracket that integrates seamlessly with your facade system.

Quality Assurance and Testing

Every production batch undergoes strict inspection, including dimensional checks and material verification. Our laboratory is equipped with a spectrometer, tensile tester, and surface testers to confirm chemical composition and mechanical properties. We perform 99.99% inspection on finished parts, ensuring consistency across large orders.

Installation and Maintenance Considerations

Installation is straightforward: anchor the bracket to the concrete wall using expansion anchors or cast-in channels, then insert the kerf tongue into the slab slot. Shims allow on-site adjustment. No special tools are required. Maintenance is minimal – periodic inspection of fasteners is recommended, and the stainless steel surface can be cleaned with standard non-abrasive agents.

Information We Use to Configure Your Solution

To prepare an accurate quotation and drawing, we need the following project data:

• Panel material and thickness (e.g., 30 mm granite)
• Required projection distance from the wall
• Wind load and panel weight per square meter
• Substrate type (concrete, steel, etc.)
• Environmental conditions (coastal, industrial, etc.)
• Quantity and delivery schedule
• Any specific standards or certifications required

With this information, we can recommend the appropriate bracket model or design a custom solution.

Frequently Asked Questions

What is the difference between up and down brackets and other cladding brackets?

Up and down brackets provide both vertical support (up) and restraint (down) for stone panels. Other brackets like Z or L may only support or align panels. This dual function is essential for kerfed systems where panels interlock.

Can you supply brackets for 20 mm stone panels?

Yes, we can customize the kerf tongue depth and bracket geometry to suit thinner panels. Provide your panel thickness and we will adjust the design accordingly.

What stainless steel grade do you recommend for coastal projects?

For coastal or high-chloride environments, we recommend AISI 316 stainless steel for its superior corrosion resistance. For inland projects, 304 is often sufficient.

Do you provide samples before mass production?

Yes, we can produce samples for your approval. Sample cost is typically deducted from the final order. Lead time for samples is about 7–10 days after drawing confirmation.

How do you ensure the brackets meet our load requirements?

We use your specified wind load and panel weight to calculate the required bracket capacity. Our engineering team can also perform finite element analysis if needed, and we can provide test certificates for material properties.
