GWELL specialising in the manufacture of PP new hollow construction template production line, the production line is my company absorbed and digested the domestic extrusion technology and independent invention and innovation and developed successfully, the unit has two single-screw extruder or single-screw plus parallel twin-screw extrusion host co-extruded through the hydraulic screen changer, moulds, shaping machine, a haul-off machine, annealing furnace, cooling box, the second haul-off machine, cross-cutting machine, conveyor composition, and the production of a number of enterprises at home and abroad to provide a full range of production equipment. For many enterprises at home and abroad to provide a full set of production equipment. 

The industry has changed from the initial O-type hollow structure, to metre type, V-type, N-type, tic-tac-toe, etc., and finally to tic-tac-toe. Tic-tac-toe structure is most accepted by the market in terms of material usage and structural performance. Its production products have smooth surface, small size error, nailable, planable, corrosion-resistant, flame-retardant and many other advantages. Compared with the traditional template, the construction template has the following characteristics: good water resistance. Even if it is completely immersed in water for many days, it will not be deformed by moisture. Acid and alkali resistance, corrosion resistance, not to rot and rust, especially suitable for basement projects, highway and railway bridge abutments and other humid environments.
