Detail Information

Black square rectangular hollow section for building structure

1. Classification of black square rectangular hollow section for building structures

1.）According to the process, it can be divided into welded steel pipes and seamless steel pipes

Seamed steel pipes are divided into spiral steel pipes and straight seam steel pipes according to the different welding seams. The two are widely used in building piling, structure, steel structure, load-bearing, drainage, and other aspects.

2.）Seamless steel pipes for building according to production methods

It can be divided into: hot rolled seamless pipes, cold drawn pipes, precision steel pipes, hot expanded pipes, cold spun pipes, and extruded pipes. Hot rolled pipes are commonly used in the construction industry.

2. Steel grade of black square rectangular hollow section for building structures

The main materials include carbon steel, stainless steel, and alloy steel. Among them, carbon steel is the most commonly used material, and the main production base for welded steel pipes is Tianjin.

3.Black square hollow section pipe for building structure customized

According to the customer's requirements, the length of the steel pipe can be fixed or scattered, and the price of fixed length is 500-600 yuan more expensive than that of scattered length per ton.

Cold bending welded rectangular steel pipe for building structures, suitable for Bridges and other structures, class ⅰ steel pipe is suitable for buildings, Bridges and other structures in the main components and bear large dynamic loads, class ⅲ steel pipe is suitable for building structures in the general bearing capacity of the occasion.
