產(chǎn)品介紹
MOLDED GRATING
Continuous fiberglass roving is placed in the open, heated mold in alternating layers, wetted out thoroughly with resin. Such a process produce an integral, one- piece construction, which offers excellent corrosion resistance and bi-directional strength as well.
PULTRUDED GRATING
The raw materials for pultrusion include a liquid resin mixture (containing resin, fillers and specialized additives) and reinforcing fibers. To achieve the reinforcement purpose, materials in continuous forms such as rolls of fiberglass mat and doffs of fiberglass roving are used.
STRUCTURAL SHAPES
The raw materials for pultrusion include a liquid resin mixture (containing resin, fillers and specialized additives) and flexible textile reinforcing fibers. To achieve the reinforcement purpose, materials in continuous forms such as rolls of fiberglass mat and doffs of fiberglass roving are used. During the pultrusion process, the raw materials are pulled through a heated steel forming die using a continuous pulling device. When the reinforcements are saturated with the resin mixture ("wet-out") in the resin bath and pulled through the die, the resin comes hardened due to the heat from the die and the cured profiles are thus formed in the same shape as the die.
FRP STAIR TREAD
Manufactured with the same criteria as the gratings, with a reinforced nosing of a contrasting color and integrated anti-slip surface. Molded and Pultruded stairtreads are available in two resin systems. Standard and custom sizes available.
LADDER & GUARDRAIL
Manufactured with the pultrusion process, the fiberglass reinforced polyester guardrail shapes contain up to 70% glass fibers, guaranteeing extraordinary mechanical properties to the system. The guardrail system is composed of various standard elements: vertical posts, fixing bases, various sections of shapes. The guardrail system is rigorously selected for its chemical resistance to aggressive agents. 相對于鋁及其他金屬結(jié)構(gòu)的爬梯和護欄,具有更好的經(jīng)濟性和耐用性能。
玻璃鋼爬梯和護欄具有重量輕,安裝方便。
產(chǎn)品無磁絕緣,可應用于更多的場合。
ACCESSORIES
