Haoyuan supply cold-formed and welded structural hollow sections for multiple purposes, ranging from versatile Tubes to ultra-high-strength Strenx Tubes. Whether you are building lifting or moving equipment or designing buildings, you can find a suitable product to best fit your needs. With structural hollow sections, you can significantly reduce the weight of your steel structures while gaining savings in material and manufacturing costs – without limiting the freedom of design.
They will help you reach higher, carry bigger loads, reach longer spans or improve your products in many other ways.
Tubes provide an unbeatable combination of higher load capacity, wide dimensional range and tailoring possibilities. Tube Double Grade is especially designed for construction purposes, combining steel grades S420MH and S355J2H.
