Steel buildings – what does your quote mean?

As with all industries, suppliers of portal frame steel buildings have their own jargon.

So, if you need clarification of the terms used in your quote here’s a quick explanation :-

Steel Buildings : Steel Framed Buildings

Steel Buildings : Steel Framed Buildings

Building Width : the measurement from one side of the building (at the gable end) to the other (usually taken from the outer edge of the cladding, but it’s worth checking with the supplier).

Building Eaves Height : the measurement from ground level to the point where the wall meets the roof.

Building Length : the measurement from one side of the building to the other along the front elevation (usually taken from the outer edge of the cladding, but again worth checking to be sure).

Column centres : the distance between vertical columns used to support the building along the front elevation.

Number of bays : the division of the front elevation of the building determined by the column centres and number of columns.

Cladding : the material that forms the outer shell of the building.  There is a choice of cladding available to finish your building envelope:-

Single skin cladding : box profile sheet steel with a plastisol coating applied to the outer side which is available in varying thicknesses to suit your building use.

Single skin roof cladding can have an anti-condensation barrier applied to the inner side of the panel if required.

Composite cladding : box profile sheet with a layer of polyisocyanurate insulation which is ‘sandwiched’ between a plastisol coated outer layer and an internal liner sheet which is usually supplied with a white finish.

Composite cladding is available in varying thickness depending on the use of the building to enable it to comply with Building Regulations.

Composite cladding can also be used to create a fire boundary.  You will need to discuss this with your supplier if a fire boundary situation exists.

Skylights : transparent profiled panels which are fitted between the regular roof cladding to allow natural light into the building.  Skylights are available in various qualities and thicknesses to suit your building.

Doors : most suppliers offer a choice of doors, the most common and economical being roller shutters.  It’s important to consider how frequently the door will be raised to determine the quality of the door and the type of operation required (i.e. manual operation or electric motor operation).

It’s extremely important to buy a door that is fit for your purpose to avoid costly breakdowns or the necessity for early replacement.

Personnel & Fire Doors :  Most buildings will require at least one personnel door or possibly more to comply with Building Regulations.  Your supplier should be able to advise you on this.
