China hollow section tubes are friendly environment in your projects

In construction projects, China hollow section tubes have many uses in structural applications involved in residential, commercial and industrial construction. For example, China hollow section tubes are widely used in greenhouse frame projects because of its cost effective, maintenance-free corrosion protection system that will be able to last for decades even in the harshest environments.

In the recent years, China steel pipe manufacturers are committed to providing customized shapes as per the specific requirements of clients in the world. For example, the elliptical hollow sections have become more popular for architectural designs. Of course, you can often find that some other shapes of hollow structural sections have been used in a variety of infrastructure construction around us. In the current steel pipe market, galvanized steel pipes are widely used in greenhouse frame projects because of its cost effective, maintenance-free corrosion protection system that will be able to last for decades even in the harshest environments. No additional preparation of the surface is required, no time-consuming inspections, additional painting or coatings are needed. Once the structure is assembled, contractors can immediately begin the next stage of construction without having to worry about the galvanized steel materials. Besides, due to its durability and anti-corrosive properties, galvanized steel pipes can be recycled and reused, which to some degree save a lot of money during the post maintenance work.

Tianjin steel pipe have great improvement in the steel industry. Tianjin rectangular steel pipe is one common type of hollow section tubes in the current steel pipe market, which is generally made by rolling plates to the required shape in a mill. And the longitudinal weld is made by a submerged arc welding process. In construction projects, rectangular steel pipes are sometimes preferred for architectural aesthetics in exposed structures in construction field due to its flat square surfaces. Tianjin rectangular hollow sections are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. ASTM A500 is the most common steel specification for hollow structural section in the steel pipe market around the world. This specification is for cold formed welded and seamless carbon steel tubing in round, square and rectangular shapes. ASTM A501 is another standard for hot formed steel tubing. If you would like to use Tianjin rectangular steel pipe in your project, it would be an excellent choice for bear resistant and consistent, which is fire resistant and does not warp, twist, split, swell or shrink. It resists dry rot and mildew, termites and carpenter ants. For increased fire resistance, the exterior of the product may be sprayed with a fire retardant material. The interior can be filled with concrete.
