Description
Production process and material
Z-type steel adopts a fully automatic cold bending forming process, with one-time roller forming throughout the process, without welding or thermal deformation. The product has high flatness, precise dimensions, and a smooth surface. The conventional material uses Q235B and Q355B low-carbon structural steel, which has good toughness, high strength, is easy to cut, easy to punch, and can be processed by on-site welding. The product can be divided into two types: black material original color and hot-dip galvanized/galvanized strip for anti-corrosion. The galvanized Z-type steel is rust-resistant and corrosion-resistant, suitable for long-term outdoor and open-air use.
Core product advantages
Compared with C-type steel, the greatest advantage of Z-type steel lies in its inclined connection structure, which is more reasonable in force distribution and has stronger integrity. The flange of Z-type steel has a consistent inclination angle, and the roof load can be evenly transmitted. It has excellent performance in resisting lateral bending, wind pressure, and snow pressure, and is particularly suitable for large-span roofs and buildings with different heights. At the same time, the material is lightweight, has a high section utilization rate, precise installation holes, and tight joints, which can effectively reduce the overall roof load and lower the cost of the steel structure main body. The cold bending forming accuracy is high, the straightness is good, the on-site installation is fast, and it significantly shortens the construction period.
Common specifications and parameters
The mainstream regular specifications on the market: Z100, Z120, Z140, Z160, Z180, Z200, Z220, etc. The wall thickness ranges from 1.5mm to 3.0mm. The fixed length can be customized according to the project from 6m to 12m, and non-standard sizes with different heights and thicknesses can also be customized according to the drawings. The product strictly follows the national standards for cold-formed thin-walled steel, with precise tolerances, no burrs or deformations on the surface.
Main application scenarios
It is mainly used for roof trusses, wall trusses of steel structure factories, warehouses, gymnasiums, exhibition halls, and other buildings with steel structures; it can also be used for roof renovation, large-span roof enclosure, lightweight steel structure supports, and auxiliary support for equipment platforms. Especially suitable for large-span, heavy-load, and uneven roof engineering. It is one of the most cost-effective and stable type materials for the current steel structure enclosure system.
