Zinc-magnesium-aluminum steel pipe
This material is particularly suitable for applications with high corrosion resistance requirements, such as civil fields like new energy photovoltaics, marine photovoltaics, prefabricated buildings, and electrical equipment, as well as marine corrosion protection fields for both military and civilian use. These characteristics of zinc-aluminum-magnesium steel pipes not only reduce the cost of later maintenance but also maintain the long-term aesthetic appearance of the facilities.
Square and rectangular tube ASTM A500
ASTM A500 is a standard for cold-formed welded and seamless carbon steel structural tubing established by the American Society for Testing and Materials. It is widely used in structural engineering due to its high production efficiency, low cost, and effective guarantee of weld quality through high-frequency resistance welding.

Spiral steel pipe is a type of steel pipe manufactured by welding high-quality steel using a spiral submerged arc welding pipe machine. Its length can be customized according to requirements, and common specifications vary. This type of steel pipe is widely used in fluid transportation, building structures, and other scenarios due to its excellent pressure resistance, impact resistance, and good corrosion resistance.
A comprehensive solution, the overall photovoltaic solution aims to achieve effective planning, design, construction, and operation of solar photovoltaic power generation systems.
Scaffolding refers to various supports erected at construction sites for workers to operate and solve vertical and horizontal transportation, and is a common term in the construction industry. They are mainly used on construction sites for exterior walls, interior decoration, or places with high floor heights where direct construction is not possible, so that construction personnel can work up and down, maintain the surrounding safety net, and install components at high altitudes. Scaffolding materials usually include: bamboo, wood, steel pipes, or synthetic materials, etc.
I-beam, also known as a steel beam (English name Universal Beam), is a long steel material with an I-shaped cross-section. It is mainly divided into ordinary I-beams, light I-beams, and wide-flange I-beams. At the same height, light I-beams have narrower flanges, thinner webs, and lighter weight. Wide-flange I-beams are also known as H-beams, and the cross-sectional feature is that the two legs are parallel and there is no slope on the inside of the legs. Ordinary I-beams and light I-beams have formed national standards.
