Import C Channel — Buy in wholesale FOB from Supplier in China

C Channel from Changsha Honest Imp. & Exp. Co., Ltd. is manufactured from Q195 mild carbon steel, supplied in two profile dimensions: 41x41mm and 41x21mm, with wall thicknesses ranging from 1.0mm to 2.5mm. The material is sourced as hot-rolled coils, then cold-formed into the C-section shape before receiving a protective zinc coating via either pre-galvanizing or hot-dipped galvanizing processes. Standard export lengths are 2.9m, 3.0m, 5.8m and 6.0m, designed to fit efficiently into 20ft and 40ft containers for international construction projects.

The steel grade Q195 is a low-carbon structural steel with typical yield strength of 195 MPa, widely specified for non-load-bearing and light structural uses such as roof purlins, wall studs and framework supports. Surface protection is critical for outdoor exposure: pre-galvanized coatings are applied before profiling and offer 80-120 g/m² zinc mass, while hot-dipped galvanized layers typical reach 200-275 g/m² for superior corrosion resistance in humid or coastal environments. Both finishes adhere to standard ASTM A653 or EN 10346 for zinc-coated steel.

Industrial buyers source these C channels for agricultural buildings, prefabricated structures and secondary framing in steel-framed warehouses. The pre-galvanized variant suits dry inland regions, whereas hot-dipped galvanized is preferred for maritime or high-moisture climates. Trade terms typically include FOB or CIF incoterms, with packaging in bundles of 50-100 pieces secured by steel straps and wrapped in waterproof paper to prevent transit damage. Confirm container loading capacity and port restrictions for 6.0m lengths before ordering.

Changsha Honest Imp. & Exp. Co., Ltd. operates from Yiju Garden, No.36 Leifeng Road in Yuelu District, Changsha City, Hunan Province. The company’s registered location places it within a key industrial hub for steel fabrication and export logistics, with direct access to Changsha’s inland port and rail networks for efficient shipments to coastal ports such as Shanghai or Ningbo. Its harbor-tier trust signal indicates a verified business presence, though the supplier currently shows a 0% response rate, which suggests recent activity or a need for direct contact via listed channels.

The supplier specializes in structural steel products, including C channels, angles and other cold-formed sections for international buyers. Its listing confirms capabilities in Q195 mild steel processing, galvanized finishing and export-ready packaging, but does not provide additional details on production capacity, certifications or in-house testing facilities. Buyers should confirm quality control procedures, such as zinc coating thickness verification and dimensional tolerance checks, before placing bulk orders.
