The Catnic BSD100 100mm box lintel is a standard-duty steel lintel for openings in 100mm internal brick or block walls, including load-bearing construction. Its box-section profile is designed to accommodate specified masonry, floor and roof loads, including point loads where appropriate. Manufactured from galvanised steel with Catnic's black Duplex corrosion protection finish, the BSD100 incorporates an integral plaster key and is available in a range of lengths to suit different structural openings.

Versatile structural applications

Where to use the Catnic BSD100

The BSD100 is designed for 100mm internal solid masonry walls, including internal load-bearing brickwork and blockwork. Unlike lintels intended only for non-load-bearing partitions, the BSD100 can be specified for a broader range of structural loading conditions where its published capacity is sufficient.

Typical loading considerations include masonry above the opening, timber floor or roof loading, concrete floors and concentrated loads. The correct lintel must be selected according to the structural design rather than assuming that every BSD100 length is appropriate for every application.

Choosing the correct BSD100 length

Catnic specifies nominal 150mm end bearings at each end. The required lintel length is normally determined by adding 300mm to the structural opening width.

For example, a 1200mm structural opening would normally require a 1500mm lintel. The selected lintel must also provide sufficient safe working load for the intended construction.

For different loading requirements, compare the following lintels and check their individual safe working load tables:

It was easy to order online, we received a phone call from driver when he was near to deliver and was left in place where we'd asked for it to be delivered.

Catnic BSD100 100mm Box Lintel

Just what I expected. A little late due to transport problems but came good in the end.

Barrie A. 5/5 Verified

Catnic BSD100 100mm Box Lintel

Poor customer service, product didn't arrive on the date it should have, when I chased I was told it was out of stock and would need to wait another week or buy an alternative and wait 3 days. We opted for the alternative as it was time sensitive and that also turned up late. I have requested compensation twice by email and once on the phone and told someone would get back to me and still nothing. Poor customer service!
