1) Good electrical performance
Fiberglass pultruded doors and windows have good insulating material, its resistivity up to 1014 ohms and it can bear high voltage without damage. Free from electromagnetic waves, no reflections of radio waves, and waves well.
2) Good sealing
Expansion coefficient of fiberglass windows and doors is lower than steel and aluminum alloy and close coefficient of expansion of the wall. Therefore, even though the temperature changes, FRP doors and windows and walls won’t crack, and there is no gap, which is suitable for area with much sand and dust.
Based on the most reliable quality, most competitive price and the best after-sales customer service, we are looking forward to cooperation with customers.
