Superior to traditional templates, such as wooden and steel ones, it has better stress intensity and deformability, which are good to engineering quality, structural safety and cost control. As a permanently dismantling-free template for concrete, it is used in civil-work of large buildings in large quantities, including tunnels, bridges, sewers, breast walls, power plants, docks, storage tanks, high-rises, ocean engineering and irregular surface modelling. After concrete pouring, the angular gomphosis on mesh openings will be embedded automatically to produce high stick force and shear resistance on joints. This mesh is easily cuttable, flexible, formable and movable, which makes it especially suitable for aloft work. The dismantling-free template is able to retain poured concrete, reduce honeycomb between gaps and the risk of sand holes without manually chipping away, roughing, cleaning or curing. Instead, re-pouring can be easily conducted thereon to combine into a firm and integral leakage protection. Mesh openings on the template may help disperse the pressure generated by mortar and concrete during pouring by 2/3, much lower than the side pressure of traditional ones. It may also be fixed directly on reinforced bars to save template frame needed, time and expenses for manpower and materials in large quantities. The template mesh still stays in the surface layer when concrete has been poured for reinforcement and preventing the surface layer of concrete from drying, shrinking or cracking. Since no iron nail and less timber is used while no oil stain or rubbish is produced, the construction site can be kept clean in adaptation to the requirements on environmental protection.
