2. Product Features
1. High strength and stability
Using high-quality alloy steel or stainless steel, after quenching, tempering and other heat treatments, the hardness reaches HRC45-60 and the tensile strength exceeds 1200MPa. Even under high load and strong vibration environment, the structure can be kept stable and effectively resist the risk of deformation and fracture.
2. Customized special-shaped design
According to customer needs and equipment installation space, various special-shaped structures such as L-type, U-type, irregular bending type can be customized. Adapt to complex assembly requirements and complete the installation and support functions that are difficult to achieve with traditional brackets.
3. Precision processing technology
Adopting advanced equipment such as CNC laser cutting and five-axis machining center, the dimensional accuracy is controlled within ±0.05mm, and the surface roughness Ra value reaches 0.4μm. Ensure perfect coordination with other components and improve the overall equipment operation accuracy.
4. Excellent environmental adaptability
Through surface treatments such as galvanizing, chrome plating, and blackening, it has excellent anti-rust and anti-corrosion properties. It can be used for a long time in harsh environments such as humidity, acid, alkali, and high temperature, effectively extending the service life of the product.

Some common specifications are as follows:

Type	Material	Maximum load-bearing capacity (kg)	Dimensional accuracy (mm)
L-shaped bracket	Alloy steel	800	±0.05
Bent bracket	Stainless steel	500	±0.05
Hollow bracket	Alloy steel	600	±0.05

III. Product Details
1. Material Type
Alloy Steel: 42CrMo, 35CrMo and other high-strength alloy steels are selected, and the comprehensive mechanical properties are good after heat treatment. It is suitable for fields with extremely high strength requirements such as aerospace, heavy machinery and equipment, and can withstand large tensile, compressive and bending stresses.
Stainless Steel: 304, 316L and other stainless steel materials are used. 304 stainless steel has good corrosion resistance and high cost performance, and is suitable for general corrosive environments; 316L stainless steel has stronger resistance to strong corrosive media such as seawater, acid and alkali due to the addition of molybdenum elements, and is often used in marine engineering, chemical equipment and other fields.
2. Size Parameters
Length Specification: According to the special-shaped structure design, the length range is 50mm - 2000mm to meet the installation space requirements of different equipment.
Thickness and Width: Thickness 3mm - 50mm, width 20mm - 300mm, different specification combinations are suitable for different load-bearing levels.
Hole position and connection structure: There are M4-M24 installation holes, and the hole position accuracy is controlled within ±0.03mm; some products are equipped with special connection structures such as dovetail grooves and T-slots to ensure close connection with other components.
3. Surface treatment
Galvanizing: A zinc protective film is formed by hot-dip galvanizing or electro-galvanizing. The hot-dip galvanizing layer is thick and has strong protective properties, suitable for long-term outdoor use; the electro-galvanizing layer is uniform and delicate, with beautiful appearance, and is often used in indoor equipment.
Chrome plating: The chrome plating layer has high hardness, good wear resistance and good reflectivity, which improves the decorativeness and durability of the product and is suitable for high-end equipment with high requirements for appearance and performance.
Blackening: A black oxide film is formed on the metal surface, which increases the beauty and improves the rust resistance. It is often used for mechanical parts with special requirements for appearance and texture.
