Roof Trusses & Engineered Floors


From our plant in Halstead, Essex, we design and manufacture whole roof solutions and engineered floors using the Wolf™ CAD based system. From the smallest garage or extension right up to housing developments and industrial buildings. Contact one of our technical staff for further details.



Wolf's Easi-Joist™ System are designed and manufactured in Halstead. These open-web floor beams easily allow service ducting and cables to be installed without cutting on site. Additional features such as being able to be top hung or cantilevered, as well as being lighter and wider than floor beams, means this is a highly versatile product is quick and easy to use, with less need for craning and manual adjustments on site.
