玻璃钢型材
拉挤玻璃钢型材是以拉挤工艺一次成型，包括方管/矩形管、圆管、棒材、槽材、L型材、工（I型）字材和板材等标准型材以及为客户定制的各种异型材。
各种型材通过一定的连接和组合制成各种不同领域应用产品。如：玻璃钢格栅、防腐平台、走道围栏、绝缘梯、冷却塔及物料支架、保温（车）厢、工具柄及其他承载结构件。
该产品是一种结构件，具有可设计性。可通过材料的选择及层铺的工艺设计改善性能，还可以对其截面和结构进行优化以达到特殊的使用要求。
拉挤型材特点：
★?广泛的耐腐蚀性
★?高强度、质量轻、抗冲击力强
★?绝缘性、透磁性
★?耐老化、寿命长、免维护
★?防火阻燃
★?尺寸稳定，无长度限制
★?安装方便，可任意切割。
