Stainless Steel L Marble Angle, L Bracket Manufacturers

We are a China-based manufacturer and supplier of stainless steel L marble angles and L brackets for stone cladding systems. Our factory in Xinghua City integrates cutting, stamping, welding, CNC machining and laser processing, producing brackets that meet the demands of modern curtain wall and natural stone facades. With an annual capacity of 8,000 tons of construction hardware, we supply project-specific L brackets to contractors, facade engineers and distributors across the United States, Germany, Italy, the UK, Japan, Australia and the Middle East.

Our L cladding system angle range is designed for direct fixing into concrete walls with expansion bolts or indirect fixing onto sub-channel systems with hex bolts. This economical and easy-to-install solution is used at horizontal joints of marble, granite and other stone panels, providing reliable support and adjustability through slotted holes and adjustable plates.

Our L Bracket Range and Applications

As a Stainless Steel L Marble Angle, L Bracket Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

We supply several L bracket configurations to match different stone panel thicknesses, joint layouts and structural requirements. Each type is manufactured from stainless steel 1.4301 (304) or 1.4401 (316) depending on the corrosion environment.

We also produce L cladding system marble clamps and corner brackets for marble corners, ensuring a complete fixing set for stone facade projects.

Engineering and Customization

Every project begins with your drawings or samples. Our R&D team develops custom L brackets to match panel dimensions, stone type, joint width and structural loads. We can adjust leg length, thickness, pin diameter, slot positions and surface finish to suit your facade system.

For example, corner brackets are specially designed for marble corners where standard L angles cannot provide adequate support. We also offer L anchors with welded ties for enhanced stability in seismic zones.

Materials and Finishes

We use stainless steel grades 1.4301 (A2 / 304) and 1.4401 (A4 / 316) as standard. For coastal or industrial environments, 316 provides superior corrosion resistance. Surface finishes include brushed, polished, or shine surface as shown in our product gallery. We can also apply passivation or other treatments on request.

Quality Assurance and Testing

Our factory operates with strict process control. We perform inspections after each step: cutting, stamping, welding, and finishing. For finished brackets, we check dimensions, angles, surface quality and material composition. Our in-house laboratory is equipped with a spectrometer, tensile tester and surface tester to verify chemical and mechanical properties.

For critical projects, we can provide material certificates and test reports. Our quality system is certified to ISO9001, and we have experience with third-party inspections by SGS, BV and TUV.

Production Capacity and Lead Times

We operate automated cutting lines, stamping presses and welding robots, allowing us to handle large orders efficiently. Our annual production capacity is 8,000 tons of building materials. Typical lead times depend on order size and customization level; we confirm delivery schedules at quotation stage.

Packaging and Delivery

We package L brackets in sturdy cartons or wooden crates to prevent damage during transit. Our factory is near Shanghai port, ensuring efficient sea freight to global destinations. Air freight is also available for urgent orders via Nanjing or Shanghai airports.

Information We Use to Configure Your Solution

To prepare an accurate quotation and technical proposal, we need the following project details:

• Stone panel dimensions and weight
• Joint width and horizontal spacing
• Substrate type (concrete, steel frame, etc.)
• Required stainless steel grade (304 or 316)
• Bracket type and any special features (adjustable plate, welded tie, kerf)
• Quantity and delivery destination
• Relevant drawings or samples

With this information, we can recommend the most economical and structurally sound L bracket configuration for your project.

Frequently Asked Questions

What stainless steel grades do you use for L brackets?

We use 1.4301 (304) and 1.4401 (316) stainless steel. For coastal or highly corrosive environments, we recommend 316 for its enhanced resistance to chloride-induced corrosion.

Can you produce L brackets according to our drawings?

Yes, we specialize in custom fabrication. Send us your drawings or samples, and our engineering team will develop the appropriate tooling and production process to meet your specifications.

What is the typical lead time for L bracket orders?

Lead time varies with order complexity and quantity. For standard sizes, production typically takes 2-4 weeks after approval of samples. We confirm exact delivery schedules when you place your order.

Do you provide samples for testing?

Yes, we can provide samples for pre-production evaluation. Please contact us with your requirements, and we will arrange sample shipment.

How do you ensure the accuracy of 45° cutting angles?

Our automated cutting lines are CNC-controlled, allowing precise angle setting. We perform multiple calibrations with professional angle measurement tools and inspect each batch to ensure consistency.
