Concrete building base
The concrete base is a fundamental part of the building and we take the time to give measurements and advice on ensuring the foundations are square and true. Besides measuring at the edges measuring the diagonals helps to ensure the base is square and true. This makes the erection of the building run more smoothly and prevents problems during the build construction. The picture below shows the concrete base in place and Initial setting up of the frame on the base
Build in progress
The side beams and frame can be laid out on the base and the sidewall frames can be prepared on the ground prior to erection.
The Framing consists of the main columns and rafters. The steel is, pre-cut and pre-punched for easy installation. These are the heaviest and strongest members that you will bolt together and fasten to your foundation. Once a few of your frames are up, you can start to bolt the secondary members to the main framework. The Secondary Framing consists of girts, purlins and framed openings. These members are pre-cut & pre-punched and provide the strength behind the wall and roof sheeting. Once all the secondary framing is in place, you can then move to the roof and wall sheeting. Depending on the height of the side panels the walls can be fixed whilst on the floor.
Completing the build
Roof and Wall Sheeting
Now that you have framing complete, the wall and roof sheeting can be completed. You will begin installing the wall sheeting first. The sheeting is screwed to the secondary framing using Lifetime self-drilling fasteners. Once the walls are done, move to the roof panels.

Complete the build by adding the trim and accessories
The final steps to finishing the steel build are to add the trim and any accessories. The trim really completes the build, not only making it more attractive but also creating a weather tight seal. Accessories such as the doors, windows and vents are installed at this time as well.
Ensure your build design is includes fire safety in its list of requirements.
When deciding on the type of building you require, don’t forget to factor in the choice of building material most suitable for your design and needs. Cost is commonly the overriding factor; yet, other factors such as weight, ease of construction, strength, sustainability, availability and fire resistance should also be taken into account before the final design is finally agreed upon.
With these additional factors in mind our steel build designs incorporate fire resistant materials throughout.
Floor base materials.
We recommend concrete bases for our building designs, as reinforced concrete does not pose a threat in the event of fire and resists the spreading of fire. Its large mass also helps to keep a more constant temperature within the building. This can make the floor base an excellent insulation and fire retardant, improving the sustainability and safety of the building.
Materials used on our walls and roofs.
Our single steel and insulated cladding is fire retardant – it has performed well in rigorous tests and British Standards, It passed the spread of Flame Test with the highest classification level and the panels successfully achieve an FAA/SAA rating. Our steel building designs comply with today’s UK fire regulations and standards.
- Use these composite steel panels for improving heat and sound insulation
Our previous blog referred to PIR composite panels which are insulated steel panels. One of customers has read our blog and asked what PIR acronym means.
PIR is an abbreviation for Polyisocyanurate, which is a thermoset plastic typically produced as a foam and used as rigid thermal insulation. PIR composite panels are typically made from foam and used as rigid thermal insulation sandwiched between the steel panels. Its thermal conductivity has a typical value of 0.16 BTU*in/hr*ft2*°F (0.023 W/(mK)).
Composite insulated panels can be used for fabrication of steel buildings. The panels are prefabricated PIR sandwich panels which are manufactured with corrosion-protected, corrugated steel facings bonded to a core of PIR foam and used extensively as roofing insulation and vertical walls (e.g. for warehousing, factories, office buildings etc.).
