Grating
Weland manufactures gratings in three different versions, pressure welded grating, A-type grating and eco-grating..Each version is available in many dimensions, different mesh widths, materials and surface treatments.
Applications for gratings
The gratings have many areas of application, both for indoor and outdoor use. The gratings offer good properties for use for e.g. walkways, vehicular gratings, entrance scrapers, fences, burglary protection, gangways for the disabled, false ceilings, etc.
Design
Questions you should ask yourself when planning gratings and that you should take into consideration include:
- Bearing capacity and load capacity of the grating
- Environment in which the grating is to be placed
- Permeable for objects, light and fluids
- Does the grating require anti-slip protection
Three different versions of grating
Presswelded grating
Weland pressure welded grating is manufactured according to the resistance welding method. Under high pressure, and at the same time high amperage, the load bearing bars are connected with the cross bars. The material at the welding points is heated and welded together without additives. This method produces welded joints with no slag. Zinc or paint therefore adheres well to these surfaces.
This manufacturing method for pressure welded grating achieves a welded joint at each connection between load bearing and cross bars. This provides the grating with extremely good durability, strength and a high bearing capacity.
Edging bars can be welded along the sides of the grating.
Pressure welded grating is made either from steel or stainless steel.
Finally, steel gratings can be hot dip galvanized or maximum rust protection.
Pressure welded grating types H3, H6 and N6 are kept in stock for immediate delivery.
A-Type Grating
Weland A-type grating is the original type of grating. A-type grating comprises flat steel that is cut into lengths for both the load bearing bars and the cross bars. The punched out load bearing bars are laid together with the cross bars to produce a mesh pattern, and the grating is supplied with edging bars on two sides.
A-type grating is made of steel, stainless steel or aluminium. Aluminium A-type grating an extremely light grating with good bearing capacity.
Finally, steel gratings can be hot dip galvanised for maximum rust protection.
A-type grating types A22x22 and A33x11 is kept in stock for immediate delivery.
Eco-grating
Weland has developed a new series of gratings, with a zinc thickness of 20 µ. Eco-gratings are adapted for environments where corrosion is not a problem. This version is the same as the traditional pressure welded grating.
The eco-grating has a thinner layer of zinc from the outset. The steel is hot dip galvanised right from the manufacture of the load bearing bars and the cross bars, as opposed to traditional pressure welded grating which is hot dip galvanised after manufacture. This procedure entails less energy consumption during manufacture. The effect of this is a reduced environmental impact, and it is consequently better for the environment.
Eco-grating has the same bearing capacity, durability and strength as a traditional pressure welded grating.
Despite its thinner zinc layer, eco-grating has good rust protection. This is useful in less corrosive environments, where wind and weather do not have such a great impact on the grating.
Eco-grating type H6 with a 34 x 75 mm mesh is kept in stock for immediate delivery.
Which variants are available?
Weland can offer gratings for many different areas of application. The gratings are manufactured in different versions with varying dimensions, mesh widths and materials. This table attempts to illustrate which type of grating you should choose.
