| Metal Stair Tread Brackets |
By Greg Vanden Berge 1/16/2009
Metal stair tread brackets are used instead of wood
cleats and for plenty of good reasons. Wood stair cleats or tread
brackets often become a safety hazard over time, as the wood starts to
deteriorate. Metal stair tread brackets, will not disintegrate as fast
as the wood it is normally attached to.
In most cases the wood stringers and stair treads will suffer from wood
rot or termite damage before the metal stair brackets become a safety
problem.
Metal stair brackets, often require lag screws instead of nails or
screws to attach the stair tread to the stair stringer. These lag screws
are normally an inch and a quarter for the stair treads, if they are
built from 2 x materials. For example a 2 x 12 or 2 x 14 stair tread
will require lag screws that will not go through the stair tread.
A 2 inch like screw will easily go through an inch and a half stair
tread. If you're building a stairway, this will be useful information.
Some metal stair brackets have four holes on each side of the metal
bracket for the lag screws, while other metal stair brackets have three
holes on each side. This normally depends on the thickness of the stair
tread and the use of the stairway. Public stairways will normally
require the stronger stair tread bracket.
During my career of building stairways, I have seen quite a few metal
stair tread brackets. Some builders had custom made brackets to meet
specific stair tread applications, while others used Simpson products,
that are more readily available to home builders and contractors.
One of the biggest problems I have noticed, using metal stair brackets
is the lag screws can loosen up over time, creating a safety hazard.
Warping stair treads, along with stair treads that split where the lag
screw is located, seem to be the biggest problems associated with metal
brackets.
Staircases are normally high traffic areas and should be maintained
regularly. Public stairways with high traffic areas should be maintained
more often. Anyone walking up and down the stairways should notify the
building owner of any problems, to prevent accidents in the future.
