ECP board, hollow extruded cement board (Extruded? Cement? Panel), which uses cement, fiber and siliceous materials as the main raw materials, is manufactured through vacuum high-pressure extrusion molding equipment, and then A new type of cement board cured by high-temperature and high-pressure steam.
High strength
The solid compressive strength can reach 60MPa, the hollow compressive strength is greater than 12MPa, and the average bending strength in the saturated state is greater than 10MPa.
Light weight
The area density of 60mm thick plate is 70~75kg/m2, which reduces the load requirements on the structure and foundation and facilitates construction.
Large size
When the width does not exceed 600mm, the maximum thickness is 120mm, the maximum length of flat panels and decorative panels is 4000mm, and the maximum length of sun visors is 4500mm.
Seismic resistance
The ECP plates are connected to the structure through bolts and are flexible connections. Even if an earthquake occurs, they can be moved through the gaps between the plates to unload and prevent the occurrence of earthquakes. Due to secondary disasters caused by earthquakes, the inter-story displacement angle reaches 1/60, which can be applied to areas with an earthquake fortification intensity of 8 degrees.
Flexible connection is adopted, the self-weight load of the plate is borne by the load-bearing angle steel, and the horizontal load is borne by the Z-shaped pendant. A gap of 5 to 15 mm is reserved between the plates. During an earthquake, the plates can be displaced and moved through the gaps between the plates for unloading to prevent the plates from colliding with each other, causing damage and falling off.
Weather resistance
The material is made of concrete, which is extruded by vacuum and high pressure. The plate structure is dense, the performance is stable, the surface water absorption rate is low, the freeze-thaw cycle can reach 100 times, and the service life is long.
Fire resistance
ECP board is a non-combustible material. The fire resistance limit of 60mm thick board is 1.00h, which can meet the fire performance requirements of buildings.
Sound insulation
ECP has excellent sound insulation performance, and the sound insulation performance of 60mm thick plate can reach 32DB.
Decoration Diversity
The boards include flat plates, striped boards, and embossed boards, and the decorative effects include clear water finishes, painted decorative surfaces, etc.
Constructability
It can be constructed without large-scale lifting machinery. It is a dry operation. Steel connectors are used to connect the wall panels with bolts, and the panel surface does not require plastering. Construction is quick and easy.

Simple but refined, ordinary is the truth. The ECP board brings out the unique heaviness, naturalness and solemnity of fair-faced concrete to its fullest potential.
This board does not contain any harmful substances and is an environmentally friendly building material product actively encouraged by the country. It has excellent properties such as high strength, light weight, fire resistance, weather resistance, earthquake resistance, and sound insulation.
The products can be used in industrial plants, shopping mall curtain walls, office building partitions, office OA floors, underground parking plants, gymnasiums, museums, office buildings, schools, train stations, subway stations, hotel partitions, and indoor backgrounds. Walls, stair treads, sidewalks, building exterior sunshades, the surface has a clear water effect, and the surface is treated with paint or real stone paint. Colored plates can also be customized, and through the organic combination of various texture changes on the surface of the plate and the design style, Combined with glass curtain walls and stone curtain walls, various styles of decorative effects are formed, making the exterior walls of the building form a unique decorative effect for the building.
The panels are used as exterior walls and installed as dry-hanging connections, similar to stone, with a keel behind them for insulation; the partition walls are installed to connect the beams and the ground, and then a T-angle line is made on the ceiling to hide the connectors. The length of the panels It is processed by the factory and transported to the site. Some special sizes can also be cut on site and can be processed by ordinary marble machines.
