Color Coated Galvalume Roof Sheet PPGL Description
The coating was aluminized zinc steel made of 55% aluminum, 43.3% zinc and 1.6% silicon. Aluminum forms a honeycomb layer around the zinc, which can protect the metal from further attack. This means that PPGL will be more durable. According to the data, the service life of PPGL roof panels under normal circumstances is more than 25 years. In addition, it is beautiful and generous, with various colors, patterns and patterns, which can meet different architectural styles. More importantly, PPGL steel has excellent heat resistance, which makes it an ideal roofing material even in hot climates. Whether it is home or investment, PPGL roof panels will be a good choice.

Color coated is in the continuous unit to cold rolled strip steel, galvanized strip steel (electric galvanized and hot galvanized) as the base plate, after surface pretreatment (degreasing and chemical treatment), with the method of roller coating, coated with a layer or multiple layers of liquid coating, after baking and cooling plate. The coated steel plate has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed, it provides a new raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry and so on. It has played a good effect of replacing wood with steel, efficient construction, energy saving and pollution prevention.

Color Coated Galvanized Roof Sheet PPGI Description
PPGI is a galvanized color-coated steel material. The coated steel sheet is subjected to surface chemical treatment, and then coating is applied and then baked. It has the mechanical strength and easy formability of steel plates, as well as the good decorative properties and corrosion resistance of organic materials. The coating has strong adhesion and can keep the color fresh for a long time. PPGI is widely used in various fields such as construction, home appliances, furniture, public facilities and transportation.

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.

H-beam is a new type of steel for economic construction. H-beam has economical and reasonable cross-sectional shape, good mechanical properties, uniform extension of each point on the cross-section and small internal stress during rolling. Compared with ordinary I-beam, H-beam has the advantages of large cross-sectional modulus, light weight and metal saving, which can reduce the building structure by 30-40%. In addition, because its legs are parallel to the inner and outer sides and the leg ends are right angles, the welding and riveting work can be saved by 25%. It is often

Flat steel,refers to 12-300mm wide,3-60mm thick,rectangular section and slightly with a blunt edge of steel.Flat steel can be finished steel,can also be used as a blank for welding pipe and thin slab for rolling sheet.Main uses:flat steel as a finished material can be used for hoop iron,tools and mechanical parts,as building frame structure,escalator.

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.

Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other. Angle steel can be composed of different force components according to the different needs of the structure, and can also be used as a connector between components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus support installation, and warehouse shelves.
