第二，钢质防火门原材料为钢板，现在市场上主要采用冷轧板和镀锌钢板两种，冷轧板价格便宜，但是阻燃的效果较差！镀锌钢板价格虽然偏高，但是隔热阻燃效果明显好于冷轧板！
Second, steel fire door raw materials for the steel plate, and now the market is mainly used in cold rolled plate and galvanized steel plate two, cold rolled plate price is cheap, but the effect is poor! Galvanized steel plate price is high, but the heat insulation and flame retardant effect is better than that of cold rolled plate!
