It is understood that the material used in this factory to make fire-proof anti-theft security doors is self-developed structural plywood to fill the domestic blank. The plywood immersed in the flame retardant has two layers of high-strength steel mesh built in the door panel, and is then subjected to fine processing after hot pressing, so that the safety door is more luxurious and beautiful, the hand feels stable, and the affinity is strengthened. The amount of formaldehyde is only 0.02, lower than the national standard of 1.5, and it is better in environmental protection. Tested by the public security department, the national fixed fire-fighting system and the refractory component quality supervision and inspection center, the fire resistance performance has reached the national level standard. Destructive tests are carried out with ordinary machinery and portable power tools, and the holes that the human body can pass through cannot be opened and cut within a specified time. The 30 kg sandbags have been hit repeatedly, and the door panels, door frames and hinges are intact. All other indicators have reached or better than the national "General Technical Conditions for Wood Fire Doors" and "General Technical Conditions for Anti-theft Security Doors". The production technology is advanced and the technology is advanced. The content is high, ranking the leading domestic level.
