Products

Shixinda is a professional manufacturer of Pre galvanized L Profile. This product is made from high-quality Q235 galvanized steel strip as the base material, and is formed by the process of galvanizing first and then cold bending and rolling. It is an L-shaped cold-formed steel section, available in equilateral and isosceles profiles. It complies with the GB/T 6728 standard. The finished product comes with galvanization protection and does not require additional anti-corrosion treatment.

ShixinDa's China Hot dip Galvanized L Profile is manufactured using high-quality angle steel as the base material, which is then treated with a hot-dip galvanizing process. This product combines the advantages of L-shaped steel structures with the corrosion-resistant and rust-preventing properties of the galvanized coating, offering excellent corrosion resistance and resistance to rusting, thereby effectively extending the service life of the components. The product's cross-sectional design ensures uniform stress distribution and superior bending performance, making it ideal for cutting, drilling, welding, and bolted assembly – resulting in efficient and convenient installation.

The Zinc Aluminum Magnesium Omega Profile produced by Shixinda Manufacturer has undergone a series of tests in accordance with national standards, including salt spray, mechanical strength, processing, and environmental simulation. In terms of the coating, the zinc-aluminum-magnesium coating can achieve a neutral salt spray duration of 5000 to 9000 hours, with a corrosion resistance 5 to 20 times that of ordinary hot-dip galvanizing, suitable for C5 level coastal high-corrosion environments, and has a design lifespan of 25 to 30 years. In the cut-off corrosion test, the cut-off sample without a sealant has a salt spray duration of 1000 hours, with rust expansion and erosion of only 0.5 to 1.2 mm. It relies on the migration of zinc-aluminum-magnesium ions to form a passivation film, achieving self-repair of the cut-off. The coating hardness is 2 to 3 times that of pure zinc coating, with excellent wear resistance and scratch resistance. After 180° cold bending and roll pressing processing, the coating is not prone to peeling or delamination, and the forming performance is excellent.

The Shixinda's China Pre galvanized Omega Profile is a thin-walled steel section fabricated in a single-step cold-bending process using high-quality hot-dip galvanized steel strip coils as raw material. Its cross-section features a "I" -shaped profile, offering structural advantages such as a high section moment of inertia and strong bending and compressive resistance. The flanges on both sides increase the contact area with the color-coated steel sheet; under the same load-bearing capacity, this section requires less material and has a lighter self-weight compared to C-section steel sections. The surface is treated with hot-dip galvanizing to form a dense protective layer, ensuring a salt spray test lifespan exceeding 1,000 hours and a service life of 15 to 20 years under conventional environmental conditions. Additionally, its cavity design, which allows for air circulation and prevents water accumulation, provides superior rust and corrosion resistance compared to square steel tubes, making it particularly suitable for use in humid or coastal environments.

The China Hot dip Galvanized Omega Profile produced by Shixinda Factory is manufactured through cold bending forming combined with hot galvanizing technology. The profile is lightweight, has excellent bending resistance, strong zinc adhesion, outstanding rust prevention and corrosion resistance, and can be punched with holes as per requirements for precise measurement. It is easy to install and widely applicable to various outdoor steel structure projects such as photovoltaic brackets, roof trusses, and greenhouse frameworks. It also takes into account both the quality and overall cost.

The Hot dip Zinc Solar Support Bracket manufactured by Shixinda is made of Q235B and Q355B high-strength steel, strictly following the GB/T13912-2020 national standards. It is fully immersed in molten zinc liquid to form a metallurgical bonding protective layer. The coating is uniform and has no dead corners. It can protect the base material by relying on the sacrificial anode principle and effectively resist outdoor wind and rain, industrial atmospheric corrosion. It can stably adapt to the 25-year design lifespan of photovoltaic power stations and requires minimal maintenance in the later stage.
