Our company currently produces five structural forms of instrument protection (insulation) boxes, among which four structural forms are made of new materials such as fiberglass, and one structural form is made of iron. Fiberglass is a new type of material composed of glass fiber and synthetic resin. The box made of it is lighter, more insulated, and more aesthetically pleasing than the box made of metal materials. It has the advantages of low specific gravity, high strength, corrosion resistance, and thermal insulation performance, and is particularly suitable for places with anti-corrosion requirements. Widely applicable to instrumentation devices in chemical, refining, textile, and other systems, as well as instrumentation devices in imported projects.
