Certainly, 2020 has not been the year that we anticipated. While we have changed some of the ways we do business, our commitment to our customers remains the same. Supporting builders with exceptional customer service and technical expertise is what we have built our business on over the past 30 years.
We believe that to fully support you we should go much further than just supplying market leading products. Our focus will continue to be delivering exceptional technical support. Our technical team provides a free design service, onsite measurement and a fast turnaround on our free quotation and specification service. They are happy to support you with free on-site measurement and technical assistance.
Keystone has developed the most extensive and complete structural steel solutions portfolio in the UK. The range includes Standard, Stainless Steel, Special and Sun Lounge Lintels, Brick Slip Feature Lintels, Light Weight Brick Headers and Sills, Roller Shutter Lintels, Hi-therm+, Windposts, Cavity Trays and the newest product in the range, a new Non Combustible Cavity Tray Lintel.
We stock more lintels than any other steel lintel manufacturer – over 800 product lines across two manufacturing and distribution centres – ensuring a quick turnaround on stock items.
ENERGY EFFICIENT DESIGN
We are aware of the challenges facing builders particularly around thermal efficiency. While our standard lintel incorporates a ‘patented’ thermal brake plate, which is castellated to prevent heat transfer across the soffit of the lintel, we have also developed the Hi-therm+ lintel range to offer an even more thermally efficient solution. Only Hi-therm offers a BBA approved ‘patented’ high performance thermal lintel that maintains rigidity to the structural steel lintel without using ‘glue’. A lintel design which incorporates a thermal break will outperform and be much more efficient than a standard lintel.
Hi-therm+ lintels use a patented combination of a polymer isolater and galvanised steel. The polymer section provides a powerful thermal break in the lintel and significantly reduces its conductivity value, with a Psi value of between 0.03 & 0.06 W/mk. As a result Hi-therm+ Lintels are up to five times more thermally efficient and are also available in the same lengths, sizes and loading capacities as the standard range of lintels.
Keystone designs and delivers special lintels in days not weeks. Special Lintels provide a solution when an unusual shape, scale or loading condition requires a bespoke design. These made- to-measure lintels enable flexibility and creativity in order to inspire endless possibility during design. Our engineers provide a free design service and can create a bespoke solution for your build. Send us your plans and we will design a structural solution.
