Composite Fiberglass FRP rectangular profile
As the composite materials ,the FRP profile have some excellent propertites ,corrosion resistant ,aging resistant ,acid and alkali resistant ,insulative ,Light-weight ,high strength ,and so on .
For the outstanding propertities ,the FRP profiles have replaced the plastic ,iron ,steel ,aluminum products ,and have been widely used
in many fields ,for example ,frame of construction ,ladder ,handrail ,fence ,etc .
