Corrugated color roof is a lightweight, strong, anti-corrosion building material. It is made of color-coated steel plate and designed in different styles, such as wavy, trapezoidal rib, tile, etc.

B500A grade steel is usually used for steel mesh products while B500B grade steel is used for steel bars. B500C steel is rarely required, and it is always worthwhile for structural engineers to check whether B500B grade steel can be used instead of B500C, because B500C usually has a significant cost overhead.

I-beam is mainly divided into ordinary I-beam, light I-beam and low alloy light I-beam. Ordinary I-beam and light I-beam flanges are thick on the web plate and thin on the outside. Ordinary I-beam, light I-beam, because the cross-sectional dimensions are relatively high, narrow, so the section of the two main sleeve moment of inertia difference is large, which makes it in the scope of application has a great limitation. The use of I-beam shall be selected according to the requirements of the design drawings.

Carbon steel H-beam is an important steel material widely used in construction, bridges, ships, machinery and other fields. Its excellent mechanical properties and welding properties make it play a pivotal role in modern industry.

Channel steel is a long strip of steel with a groove-shaped section, which is a carbon structural steel for construction and machinery. It is a section steel with a complex section, and its section shape is groove-shaped. Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

PPGL roof panels are an excellent building material. Its weight is only 1/30 of the traditional concrete roof, which is easy to install and greatly shortens the construction period. It also maintains the strength and durability of the steel, allowing it to last more than 25 years under normal conditions.

Deformed bar, also known as rebar (short for reinforcing bar), is a steel bar or mesh of steel wires used as tension devices in reinforced concrete and reinforced masonry structures to strengthen and hold the concrete in tension. Deformed bar’s surface is often patterned to form a better bond with the concrete.

HPB300/HRB335/HRB400/HRB500 Reinforcement is a European standard steel bar. Generally, GB1499.2-2007 standard deformed steel bars are made using the hot-rolled method, meaning that these are the most common types of deformed steel bars. These are available in different lengths and sizes, all the way from 6 mm in diameter to 50 mm in diameter. When it comes to length, 9 m and 12 m are the common sizes.

I-section steel is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its section is the same as the English letter "I". Since the various parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structure in all directions.
