Steel Superior Construction Features

[1] Portal Frame Connector Plates.

Twinspan portal ridge and knee connector brackets are pressed from thick zinc galvanised steel and are fixed through pre-punched holes with high tensile bolts to ensure the strongest possible connection.

[2] Purlins and Girts

Twinspan purlins and girts (the members that the roofing and wall cladding are fixed to) are fixed to the sides of the portal frame using high performance Tech-screws and bolts.

This method of fixing is not only strong but it means that you have more usable space inside your building.

[3] Hold Down Brackets

These are slotted for ease of fixing to both the portal leg and to the concrete slab.

[4] Roof Lights

Fitted as standard on all buildings, 2 per Bay allowing extra natural light into your building.

[5] Roof Pitch

Twinspan buildings have a standard 11 degree pitch roof which is not only strong but is aesthetically pleasing. Other pitches are available.

[6] Roof and Wall Cladding

Twinspan’s roof and wall cladding is roll formed from high tensile steel. Your roof and wall cladding are galvanised with a 200 micron plasticol coating in a wide range of colours. This method ensures a life expectancy of over 40 years.

[7] Gutters & Barges

Twinspan gutters and barges are roll formed in a unique profile that not only adds strength but also provides an attractive finish to your roof. Twinspan gutters and barges are available in a wide range of colours to compliment your building.

[8] Windows

Windows may be purchased wholesale and fitted to all buildings.
Fitting instructions available on request.

[9] Personal Access Door. (PA Door)

Our doors are built to last and come complete with security lock.

[10] Flashings

All door openings and corners are protected with coloured plasticol coated 0.7mm galvanised steel, roll formed flashings to ensure a neat and weather tight finish. The edges of the flashings are double folded to ensure there are no exposed sharp edges.

[11] Doors

Twinspan offers a wide range of doors including roller and sectional doors in sizes to fit most applications.

Doors can be fitted into the side or the gable end of standard portal buildings. Please advise your Twinspan outlet of any particular door clearance size requirements you may have.

Absorb

The solution to condensation problems.

Condensation is a problem in roofing leading to the formation of water droplets that run and drip, not only causing annoyance to the occupants but causing all sorts of damage to equipment and stored materials.

In cases where thermal insulation (composite panels) is not cost effective, lining the roof of the building with Twinspan-absorb is the solution. When the roof panel is cooled by the outside air, the non woven film bonded to the underside absorbs the condensing water vapour.

The absorbed water is then eliminated by the process of evaporation during the day caused by a combination of the rising roof temperature and an efficient ventilation system.

Twinspan-absorb can therefore be used in most well ventilated buildings, factory units with day time activity and in buildings with minimal heating.

Quality is our Strength

Our range of buildings are designed to comply with all the relevant codes as set down by the UK statutory authorities. Our Twinspan Computer Software Package generates plans and specifications to suit the above codes.

The Twinspan specification sheet shows all relevant information for your particular building including the size and gauge of all the structural steel being used and the purlin and girt spacings for your particular building.

The Twinspan generated Bill of Material with each building ensures the correct quantity of materials are supplied for each job. Twinspan generated elevation drawings and specifications are available with each building for you to submit for building approval.

A large range of standard colours are available so that you can personalise to suit yourself. Choose different colour walls, roof, doors and trim at no extra charge. Most of our range of quality steel buildings feature a galvanised Portal Frame System for durability, strength and simplicity in construction.

Environment

Environmental Policy		Recycling & Sustainability
	We are committed to minimizing the environmental impact of our operations and our products through the adoption of sustainable practices and continuous improvement in environmental performance.		Designers and builders have long recognized and lauded steel for its strength, durability, and functionality. Increasingly, however, architects are recognizing steel ’s important environmental attributes, especially its high recycled content and high reclamation rate.
	We believe that respect for the environment is critical to the success of our business and our aim, therefore, is to continuously improve our performance.		Recycling saves money while conserving energy and resources, as well as reducing solid, liquid, and gaseous wastes. Recycling also helps to spread the energy impact of the original extraction and manufacturing of the material over infinite generations of new steel.
	We strive to continuously improve the environmental performance of our processes and products through research and development of new technologies, preventing and reducing emissions and releases, minimising waste and controlling noise.		Steel construction materials contain at least 28 percent recycled steel and are completely recyclable. Using steel takes the pressure off renewable resources: a typical 2000-square-foot home requires about 40 to 50 trees, about an acre’s worth, to build with wood. With steel, only the equivalent of about six scrapped automobiles are needed.
