Benefits of Steel over alternative buildings…

  • Steel building components are manufactured to consistent quality and exacting tolerances.
  • Steel is manufactured to precise and uniform shapes.
  • Steel does not promote mould and mildew leading to minimal ongoing maintenance.
  • Steel has one of the highest strength to weight ratios of all building materials.
  • Steel can be engineered to meet the snow load and wind zones required by building regulations.
  • Higher strength means that on-centre distances can be wider in steel buildings reducing the amount of material and labour required - thus reducing costs.
  • Steel strength allows for taller walls.
  • Steel and metal framing can reach greater spans than other materials creating larger open spaces.
  • Steel can work well on its own or in combination with other materials.
  • Steel frames are lighter than traditional concrete and masonry leading to reduced footing and foundation requirements.
  • Steel building components can be as much as 50% lighter than wood.
  • Steel building components do not rot like wood construction can.
  • Steel framing connections are much stronger than wood connections.
  • A steel or metal framed building produces much less waste than wood. An average wood framed home generates about 50 cubic feet of waste in the landfills compared to about 1.5 cubic feet for steel or metal.
  • Steel is non-combustible. In many cases, your insurance premiums will be lower because of this.
  • Steel is 100% recyclable. 60 million tons of scrap steel are recycled every year which is more than paper, aluminium, glass and plastic combined.

Steel Buildings supplied by John Sisson Contracting are portal framed buildings. Portal framed buildings are steel buildings that are constructed in bays. In simple terms ‘the longer the steel building the more bays there will be’. Our steel building assembly crew will construct two portal sections consisting of two posts and two rafters that are joined by brackets forming a portal. Then the two sections are joined together by attaching purlins horizontally between the sections to make a bay. This method is continued depending on the desired length and/or bays within the steel building. Steel buildings constructed from this portal frame method are strong, durable, inexpensive and easy to erect.

Staff training is important to us and we encourage our construction teams to gain Construction Industry Training Board qualifications.

We are accredited under the SAFE contractor and CHAS schemes and we belong to the Constructionline register of UK pre-qualified local and national construction-related suppliers.

We are proud to be accredited with the ISO 9001 quality standard.

We give top priority to product quality and staff training, and to health and safety standards.

Our design and technical staff are trained to meet Construction (Design and Management) (CDM) regulations.

Our welders are tested to British Standard (BS EN) 287-1, with welding procedure BS EN 15614-1. Foremen and supervisors are qualified to Institution of Occupational Safety and Health (IOSH)) standards.

Erectors are qualified in the Construction Plant Competence Scheme (CPCS). John Sisson Contracting is registered under the International Organization for Standardization (ISO) standard 9001, the internationally recognised standard for quality management.

The Benefits of using Cold Rolled Steel Buildings…

The steel used in our steel portal frame buildings is cold rolled steel. This type of steel is both high tensile and very durable. Cold rolled steel is incredibly strong, but lighter than hot-rolled steel. This means the combination of cold-rolled steel and portal frame method allows relatively small steel sections to span long distances. In addition this reduces the cost of materials and due to the reduction in weight, it allows for innovative construction techniques to be employed. Lifting equipment is generally not required to construct our steel buildings. This will result in shorter construction times, reduced erection costs and higher quality.

Cold rolled steel purlins’ profile can be stacked into very compact loads. This allows a large building to be transported in a relatively compact package, significantly reducing transportation costs.

Cold Rolled Steel Sections are pre-cut to sizes with fixing points predetermined by our steel building design, effectively providing your steel building in kit form.

Our steel buildings are fully galvanized as standard ensuring durability without the extra costs of galvanizing, required with hot rolled steel structures.

The end result is a superior steel building, engineered to exacting British Standards and designed by state of the art software which allows our customers flexibility to have a building to suit specific requirements.
