WMC is of expertise in developing and specializing in preparation and purification of metals, oxides and compounds to 4N, 5N, 6N and 7N purity which is in fabricated form of lump, rod, granule, powder, sheet, wire and ingot. All the material is qualified by the analysis of ICP-MS, GDMS and other advanced instruments domestically and internationally.
It is always our goal to be a consistent, reliable and an affordable source for global material requirements at any time. Antimony is a hard, brittle crystalline metal with silvery white and lustrous color. High purity antimony of 99.99%, 99.999%, 99.9999%, 99.99999% (4N 5N 6N 7N) is primarily used in the manufacturing of thermoelectric devices, infrared detectors, high purity alloys, electronic cooling elements, III-V compound semiconductors gallium antimonide (GaSb) and indium antimonide (InSb), and as the dopant of single crystal silicon and germanium growth.

High Speed self-Recovery Rapid doors are the technological evolution of old, PVC high speed doors or heavy folding doors, now obsolete and not suited to today's industrial needs.
High-quality panels, the resistive safety edge fitted to the bottom edge of the door, photocells and barriers make this product both safe and durable, being totally self-repairing, thanks to its special [Anti Crash System".
This door designed with a perimeter structure in galvanized or stainless steel, which is ideal for sliding panels. The door panel rides effortlessly within a track, thanks to the special profile and hinge designed by us, requiring low maintenance. The panel is rolled up on a roller placed within the upper crossbeam.
The door can be equipped with a counterweight or ups batteries, to fully open the door in case of power failure, and can also be equipped with large transparent sections to create a brighter and safer working environment.
Self-Repairing Door Curtain made of reinforced PVC, with flexible weighted soft bottom edge.
The edge of curtain has continuous injection molded teeth that then move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames.
