Hot Drawn Steel Unistrut 41x21 Channel Cold Bending Roll Forming

Hot-drawn steel 41x21 Metal Strut Channel Wholesale customization available construction applications

Product Description:

Hot-dip galvanized 41×21C steel section is a lightweight steel structural profile that has been cold-formed and undergoes hot-dip galvanizing for corrosion protection. The cross-sectional dimensions are precisely 41mm×21mm. It features high strength, strong corrosion resistance, and ease of installation, and is widely used in fields such as photovoltaic supports, cable trays, seismic support hangers, and building curtain wall supports. It is an extremely cost-effective lightweight load-bearing component in construction projects.
The product is made from high-quality Q235B low-carbon steel and processed through a continuous cold bending forming process. The forming accuracy is high, with a cross-sectional tolerance of ±0.3mm and a straightness of ≤1.5mm/m. The structure is compact and has excellent rigidity, with outstanding bending, torsion, and shear resistance. It can stably bear various lightweight loads and meets the support requirements of different scenarios.

The product specifications are complete, with standard wall thicknesses of 1.5mm, 2.0mm, and 2.5mm. Customized wall thicknesses of 1.0-3.0mm are available. The length is default 3m or 6m, and can be customized as needed from 1m to 12m. The cross-section comes with standard long round holes (14×28mm), with adjustable hole spacing. Combined with dedicated connecting pieces, it can achieve boltless screw connection, making installation convenient and efficient, significantly shortening the construction period and reducing labor costs

Trial scope:

Its application scenarios are extensive. It can be used as the diagonal supports for the roofs or ground supports of photovoltaic power stations, the hangers and brackets for cable trays, the main bodies of seismic support and hanger systems for mechanical and electrical pipelines. It can also be used for lightweight supporting structures such as building decoration, equipment bases, and shelves. It is suitable for various scenarios including industrial plants, commercial buildings, and outdoor projects. With stable performance and long service life, it has become the preferred material for various lightweight supporting projects.
