Product Features
1. High-strength material
Select high-quality alloy steel, stainless steel and other materials, and undergo special forging and heat treatment to greatly improve strength and toughness. The yield strength of the alloy steel bracket exceeds 600MPa and can withstand heavy loads; the stainless steel bracket has excellent corrosion resistance and its service life is extended by 3-5 times in harsh environments such as moisture, acid and alkali.
2. Precision machining technology
Adopting CNC lathe for precision machining, the cylinder diameter tolerance is controlled within ±0.02mm, and the cylindrical error is less than 0.01mm, ensuring perfect fit with other components. The surface roughness Ra value reaches 0.8μm, which reduces friction loss and improves operation stability.
3. Flexible installation design
There are various threaded holes, pin holes or positioning grooves at both ends of the bracket, which support top hoisting, side fixing, bottom support and other installation methods. Users can assemble quickly as needed, saving installation time and labor costs.
4. Diverse specifications

Provide a variety of specifications, with diameters from 10mm to 200mm and lengths from 50mm to 1000mm to meet the support needs of different scenarios. Some common specifications are as follows:

Diameter (mm)	Length (mm)	Material	Maximum load weight (kg)
20	100	Alloy steel	500
50	200	Stainless steel	1500
100	500	Alloy steel	3000

Product Details
1. Material Type
Alloy steel: Mainly 45# steel, 40Cr, etc., after quenching and tempering, the hardness reaches HRC35 - 45, with good comprehensive mechanical properties, suitable for conventional industrial heavy equipment support.
Stainless steel: 304, 316L, etc. 304 stainless steel has good corrosion resistance and high cost performance, suitable for general corrosive environments; 316L stainless steel adds molybdenum elements, has strong resistance to strong corrosive media such as chlorides and seawater, and is often used in marine engineering and chemical equipment.
2. Size parameters
Diameter specifications: covering 10mm, 12mm, 16mm, 20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 80mm, 100mm, 120mm, 150mm, 200mm, etc., to meet different load requirements.
Length: 50mm - 1000mm optional, short version is suitable for internal support of compact space equipment, long version is used for connection and support of large frame structure.
Aperture and thread: The aperture at both ends is adapted to the diameter, the thread specification is M4 - M24, and high-precision processing ensures tight connection.
3. Surface treatment
Blackening treatment: Chemical oxidation forms a black oxide film, which increases the beauty and rust resistance, and is suitable for indoor equipment with low requirements for appearance.
Galvanizing treatment: The hot-dip galvanizing layer is 8 - 12μm thick, with excellent rust resistance, suitable for outdoor use; the electroplated galvanizing layer is uniform and bright, and is often used for indoor decorative equipment.
Chromium plating: The hardness of the hard chrome plating layer reaches HV800 - 1000, which improves wear resistance and corrosion resistance, and gives a high-grade metallic luster, suitable for high-end equipment and precision instruments.
