Joining Durbar

Welding and mechanical fixing are typical methods of joining and fixing Durbar.

In general, you can use Durbar in the same way as plain plate, always being mindful of the location of the pattern.

Information about using steel plates for flooring and stair treads, including requirements for construction and fixing, are contained in BS 4592-5 : 2006, Industrial type flooring and stair treads – Part 5: Solid plates in metal and glass reinforced plastics (GRP)—Specification.

Welding
Durbar can be welded readily using any of the conventional welding processes, including MIG/MAG, manual metal arc and TIG, to create strong, tough joints.

The strength of the filler metal can be matched to that of Durbar or a lower strength filler can be used, depending upon the performance required in the particular application.

When Durbar is welded, there is a very low risk of hot cracking due to the low levels of carbon, phosphorus and sulphur, and a low risk of cold cracking due to the relatively low carbon equivalent.

Fixing
Users should see the standard referred to above. Some key points about fixing Durbar are:

• Support plates on all sides and extend them at least 25mm beyond the supports.
• Plates may be welded down, bonded, bolted, or bolted and bonded using countersunk screws.
• For encastré plates bolted to supports, bolt them about 100mm from their corners and at centres not more than 500mm. Drill and countersink them before bolting them to the supports.

One example of a fixing used for steel floor plate is the Floorfast bolt made by Lindapter, which can be seen at www.lindapter.com in the floor fixings section.
