Pressure plate in the 1930s in the United States in the early 1980s, Wuhan Iron and Steel, Baosteel first introduction of color coated steel plate production line, from China began to domestic Caitu pressure plate used in industrial buildings, factories, national cotton and food storage, local development District plant. Color coated steel sheeting applied technology developed rapidly, expanding range of applications, the amount is increasing.

Into the 21st century, high-speed stable development of China's national economy, and color coated steel sheeting from the general industrial buildings around the large, public buildings, such as airport terminals, railway stations, stadiums, concert halls, large theaters, the 2008 Olympic Games venues. Building roof, floor and wall board type power and connect more reasonable, more scientific construction methods like performance more galvanized plate, aluminum-magnesium-manganese alloy plate, titanium plate, stainless steel, etc. R & D, greatly enhanced the level of applied technology of the subtypes metal plate.

Board structure and standards undercut structure, the second generation of the pressure plate of the fastening structure and fasteners hidden connections; CLOSED the Cored The existing mature application; coating plate and pressure plate (substrate) to increase the aluminum plate, galvanized aluminum varieties, coated sheet and partial polyvinyl fluoride (PVDF) coated plates, weather polyester coated board (HDP); international "continuous heat galvanized steel sheet and strip, color coated steel sheet and strip, steel construction quality acceptance gradually revised.

Characteristics of the pressure plate

(1) beautiful novel, rich colors, decorative, flexible combination, can express different architectural styles;

(2) light weight (~ 10kg / m²) high strength (yield strength of 250 ~ 550MPa), good skin stiffness, waterproof seismic performance;

(3) factory product quality

(4) construction, easy installation, reducing installation, transportation workload, shorten the construction period;

(5) The pressure plate is an environmentally friendly building materials, recyclable, and promote the use of steel sheeting in line with the policy of sustainable development in national economy;

(6) monomer material prices are compared with concrete or masonry cladding, durability is poor.

Classification of the pressure plate

The pressure plate is usually based on the application site, the plate wave height, the lap joint construction, and materials, there are a variety of classification. Common classification of the following categories:

(1) classified according to the application site - divided into the roof, wall panels, floor boards and ceiling panels. The use of color steel plate for wall decoration board, building decorative effect is relatively new and unique.

(2) wave height classification - is divided into the high-wave plate (wave height ≥ 70mm), medium-wave plate with low-wave plate (wave height <30mm)

(3) classified by the substrate material - into the substrate of hot dip galvanized, hot galvanized and hot dip galvanized aluminum plate.

(4) slab constructed classification - divided into the lap, undercut and withhold constructed. Which undercut withheld, high-wave plate is preferable to make the roof higher water requirements; lap, high-wave plate galvanized sheet with floor cover; lap of the low-wave plate is preferable to make wall board.
