Import Galvalume — Buy in Bulk from Supplier in China

Galvalume supplied by Cus-steel Group Co., Ltd. is a pre‑painted steel sheet that combines an aluminium‑zinc alloy coating with a cold‑rolled steel substrate. The supplier lists a thickness range of 0.18 mm to 4.5 mm, allowing selection for thin roofing panels up to heavy‑duty structural components. Widths are offered in a variety of standard sizes, and the material is described as lightweight, which reduces handling effort on site. The product’s corrosion resistance is positioned as superior to conventional hot‑dip galvanised steel, extending service life in exposed environments.

The coating consists of approximately 55 % aluminium and 45 % zinc, a composition that is typical for Galvalume and provides a sacrificial barrier against moisture. Industry data shows a typical coating thickness of about 55 µm, delivering a corrosion rating comparable to ISO 12944‑C for coastal exposure. Standard tensile strength for the underlying steel is around 310 MPa, while the density remains near 7.85 g cm‑3, giving a weight of roughly 7.85 kg per metre for a 1.0 mm sheet. These figures align with common specifications for building‑grade Galvalume used across the construction sector.

Common applications include roofing panels, wall cladding, HVAC ducting and other exterior building elements where long‑term rust resistance is required. Buyers such as contractors, fabricators and project developers typically request FOB or CIF terms and may negotiate minimum order quantities that match their production schedule. Although the listing mentions flexible MOQ options and packaging solutions, exact lot sizes and payment conditions should be confirmed directly with Cus-steel before contract finalisation.

Cus-steel Group Co., Ltd. is located at Room 1006, Chuangye Building, 136 East Zhuhai Road, Huangdao Zhengzhou 450000, Henan, China. The supplier is classified as an imported tier with a harbor trust tier, indicating that the company operates under the oversight of Chinese customs authorities. Response metrics show a 0.00 % response rate and no recorded average response time, suggesting that communication may be limited unless initiated by the buyer.

The company’s current listing focuses exclusively on Galvalume steel sheets and does not provide additional product lines or detailed corporate history. No information about the firm’s year of establishment, employee count, or past client portfolio is disclosed, so buyers should request any missing corporate documentation directly if required for due‑diligence.
