Durable Cold Formed Steel Profile for Structural Applications

ShixinDa factory’s Pre galvanized Z Channel are manufactured using high-quality galvanized steel strips conforming to national standards as raw materials, processed through an automatic cold bending unit with integrated rolling forming technology to produce sections in standard Z-shape. These profiles serve as specialized load-bearing purlins for roofs and walls in steel structure projects, offering a comprehensive range of specifications from 100Z to 250Z, with thicknesses ranging from 1.2 mm to 3.0 mm; they also support custom length cutting and standardized pre-drilled holes.

Abstract: ShixinDa's Zinc Aluminum Magnesium C Channel, featuring a high-quality ZAM ternary alloy coating and an fully automated precision cold-forming process, offer a significantly longer service life compared to traditional hot-dip galvanized C-section steel, making them suitable for a wide range of structural steel applications and photovoltaic projects. In low-corrosion environments such as inland dry industrial sites and mountainous photovoltaic installations, standard ZM275-specification products can achieve a service life of 25–35 years; in moderately corrosive environments—such as suburban areas with high rainfall or agrivoltaic systems—these products can operate stably for 20–28 years.

The Hot dip Galvanized C Channel produced by Shixinda Manufacturer is cold-formed from Q235B and Q355B steel plates and then fully heat-dip galvanized to form standard C-shaped thin-walled steel sections. It is specifically designed as outdoor load-bearing components for factories and photovoltaic projects. It is mainly used as roof trusses, wall beams, and main and secondary beams of photovoltaic supports, bearing the load of enclosure and light support.

Shixinda specializes in manufacturing this Pre galvanized C Channel. It is made from standard DX51D + Z galvanized steel strips as raw materials and is formed through a fully automatic cold bending machine with a single roller press process. It is a prefabricated anti-corrosion lightweight cold-formed section that does not require additional post-corrosion treatment. The product is mainly used as roof purlins for factory buildings, wall beams, photovoltaic supports, breeding shed frameworks, and pipeline load-bearing brackets. It can withstand roof wind and snow loads and is used to construct building enclosures and support systems for new energy.
