Electro-welded Steel Grilles (Type Tramex)

Tramex grilles are usually placed on vents to let air pass through its openings, pipes or gates. Besides, these grilles are placed on the floor in order to let water flow through them.

Tramex grilles are composed of 2mm thick laminated sheets. These kinds of grilles are provided and structured to be toughness to the weight of people or vehicles. In addition, the galvanized treatment prevents its oxidation and deterioration of the steel grille.

They are exist three types of treatments:

Hot Galvanized according to UNE in ISO 1461:

The regulation defines the hot galvanized as the formation or zinc coating in steel. Steel is submerged in a 450º molten zinc bath that causes that zinc be stuck on steel surface.

The primary aim of this procedure consists in prevent the steel rusting and corrosion that could be caused by moisture and environment pollution.

Thermo-lacquer according to UNE in 15773:

It is a process that applies a powder covering in thin layers to metal prepared to be placed into an oven and bakes it.

The architectural quality of polyester powder allows giving the better characteristics for a clean process of powdering and provides to good tough with a better aesthetical.

Duplex System (Hot Galvanized + Thermo-lacquer according to UNE in 15773):

We apply both procedures sequentially. Hot galvanized and thermo-lacquer. It is based on apply polyester powder to galvanized surfaces when is required a better result in corrosion proofing or when seeking a better aesthetical.

The grille is made and designed as an electro-welded grille of 34x38mm, plate 50×3 and has a spherical shape between rotated 5 mm. The usual dimensions are usually 500x500mm.

Can be designed with padlock lug nut
