The width of thin plates is 500~1500 mm; the width of thick plates is 600~3000 mm. Thin plates are divided by steel type, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plates; according to professional use, there are plates for oil drums, Enamel plates, bulletproof plates, etc.; according to surface coating, there are galvanized sheets, tin-plated sheets, lead-plated sheets, plastic composite steel sheets, etc.

Channel steel is divided into ordinary channel steel and light channel steel. The specifications of hot-rolled ordinary channel steel are 5-40#. The specifications of hot-rolled modified channel steel supplied by agreement between the supplier and the buyer are 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed panels. Channel steel is often used in conjunction with I-beams.

T-shaped steel is a kind of steel cast into a T shape. It is named because its cross section is the same as the English letter "T". The code of T-shaped steel corresponds to that of H-shaped steel. TW, TM, and TN are used to represent wide-flange T-shaped steel, medium-flange T-shaped steel, and narrow-flange T-shaped steel respectively. The expression method is also the same as that of H-shaped steel.

I-beams are structural beams that are shaped like the letter "I" and are commonly used in construction for their strength and durability. I-beams are widely used in buildings or other metal structures. When selecting I-beams in structural design, reasonable I-beams should be selected based on their mechanical properties, chemical properties, weldability, structural dimensions, etc.

H-shaped steel is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H".

School projects include teaching buildings, student dormitories, playgrounds, kindergartens, etc. The main buildings all adopt prefabricated steel structure technology and take the advantages of prefabricated steel structure buildings.

Steel structure warehouse is a new type of light steel structure building system. The main steel frame is composed of H-shaped steel, Z-shaped steel and U-shaped steel components. The roof and walls are made up of various panels and other components such as windows, doors and cranes.

Steel structure building is a new type of building system that bridges the industry boundaries between the real estate, construction, and metallurgical industries and integrates them into a new industrial system. This is the steel structure building system that industry insiders are generally optimistic about.
