The W strip is named because its cross section resemble the letter W, which is made of Q235.

W steel strip, also called roof steel strip, is a section steel product formed by continuous cold forming roll of multiple rolling mills with longitudinal shear strip as raw material.

Product features:

Model selection can be made according to different geological conditions and operating environment.

The modulus of bending section is increased by 37 times, and the modulus of downward section is about 2.75 times of that of upward section. Therefore, the rockbolt drill is used to jack up during installation.

Compared with other types of steel tape, W steel tape is more difficult to tear, and the steel degree is larger, about 70 times higher.

Hardening in the process of cold rolling increases the tensile strength by 12%-15%.

High utilization rate for cross section, low price of saving materials.

Four major features:

High strength alloy strip steel is used as raw material. Through cold pressing into a W-shaped strip, according to the length of the requirements of truncation, and then drilling.

It has higher rigidity and strength.

W steel strip bending section modulus increased 54 times.

The hardening effect of W steel strip during cold pressing can increase the tensile strength by 28-46%.

Performance specifications:

Common width?180mm, 200mm, 220mm, 250mm, 280mm, 300mm.

Common thickness: 2.5mm, 2.75mm, 3.0mm,

Common aperture: 40mm*60mm, 30mm*70mm.

The length of W steel belt can be customized according to the actual needs of customers.  

W steel belt connects scattered bolts to form a single integrated bearing structure, which significantly improves the overall effect of bolt support, and has a better application effect in incomplete roof rock. It has the advantages of reducing supporting cost and saving supporting steel.
