About Us

Bonnar Engineering Ltd was founded in the year 1959 with the manufacture of gates and railings, electric welding and general repairs. Subsequent to this the fabrication and erection of structural steelwork, incorporating portal frames, steel trusses, Purlins, sheeting, cladding, gutters and insulation quickly became the main thrust of the business. The Company became renowned for its capability in structural steelwork and rapidly built up an excellent reputation in this field.

Due to a substantial expansion in trade it became necessary to move to a new larger premises in 1974. Further expansion became necessary in 1982, and in 1998, as a result of ongoing progress and continuing improvement, a new 35,000ft2 premises was constructed at our current location.

A highly competent workforce and a state of the art premises have ensured that the Company has the ability to deliver a service, which is unsurpassable. Large volumes of steelwork are turned out from the factory floor each week and the many projects completed by Bonnar Engineering are testimony to our expertise in this field

Our investment in Quality and Safety sets us above our competition and our implementation of technology allows us to track each piece of steel from drawing to installation. The combination of these elements enables us to deliver projects of the highest quality on time and cost efficiently.
