2 build On OUr strength company HisTOrY Stressline Limited manufactures a wide range of structural building products for domestic and commercial sectors. Stressline is the first choice for builders, contractors & specifiers across the UK because of its ability to deliver high quality products on time and at the right price, ensuring projects are not disrupted and work is completed on time. Stressline also supply direct to site or through a supply chain of merchants across the country, making sure their products are always highly accessible. Stressline s customers choose them over other structural product manufacturers because of the promise to always be competitive on price, the mixed order delivery capabilities and the high quality service. build On OUr strength introducing OUr extended LinTeL range Stressline s in-house technical and manufacturing departments have worked hard over the last 12 months to deliver an extended range of steel lintels. The new lintel guide clearly lays out the extended standard range of steel lintels, and for the first time the prestressed concrete lintel range, allowing the customer the utmost flexibility and choice to satisfy their lintel requirements. structural building PrODUcTs This extended steel lintel range perfectly compliments our other structural building products. We manufacture a complete range of prestressed concrete products in addition to the prestressed concrete lintels; including flooring beams (suitable for concrete or insulation infill), hollowcore flooring, and walling panels. Precast items available include padstones, stairflights and landing slabs, although our extensive design and manufacturing resource enables special projects to be produced cost effectively. Our non structural range of products includes fencing and landscape walling products. 2

4 Service Delivery OUR COMMITMENT TO YOU SALES & SUPPORT Our area sales managers and sales technicians are able to assist you with your specification needs. Whether advice is needed for a single lintel, or a comprehensive take off and pricing schedule for a multi dwelling development, our team is here to help. The brochure and website outline our ranges and offer tools to assist your selection. In addition, our unique ability to manufacture a range of structural building components offers the specifier and the buyer a complete solution for structural flooring (both beam and hollowcore), steel and concrete lintels and structural precast products, including padstones, staircases and landings. Our flexible design and manufacturing facilities enable your special lintel requirements to be produced quickly and efficiently. OUR PRODUCTS Our comprehensive range of standard steel and concrete lintels offers design capability for all circumstances, designed to the relevant BS EN standards and with the reassurance of BS EN ISO: 9001 (2008) management standard. The cavity lintel range is supplied with captive insulation to ensure that it is not displaced. The fabricated range is manufactured with a proven non-welded method creating a secure connection that has not compromised the galvanised protection. Our range of prestressed concrete lintels is manufactured using machinery and processes designed by our own engineers. This has enabled the maximum strength to section available, whilst producing high volumes of consistent quality products. Our Promise Stressline understand the day-to-day challenges you face on a building site and the importance of working with a supplier you can trust. Our promise is simple to deliver competitively priced products, on time, to the required specification. Accreditations Stressline has an on-going commitment to improving both product and management systems; 19: BSI Quality Assurance Accreditation to ISO : BS EN ISO 9001: : ISO 9001:2008 Environmental and Sustainability We recognise our responsibilities to the environment. We are committed to developing, implementing and reviewing our management and operational policies and procedures to minimise our environmental impact. Our IMS includes all our compliance policies and achievement targets. From our ongoing environmental and sustainability commitments we have continued to achieve significant reductions in our impact as manufacturers and distributors. One major environmental benefit shared with our existing customers is the ability to source our complete range of products and for them to be delivered as a mixed load on one vehicle, instead of separate deliveries which creates wasteful and unnecessary movements. service DELIVERY DELIVERY All our products are delivered on flat bed articulated or rigid lorries, with the option of either self offload or crane offload. Depending on the customer s requirements both steel and concrete lintels are packaged in stock packs or in consignment loads (with the option of house plots and locations marked on the product). As we are located centrally we are able to supply all our standard products nationally, with delivery typically three to eight working days. BACK to Contents page 4

Additional requirements for composite extra Heavy Duty (cxhd) lintels Ensure that the inner leaf channel is fi lled with well cured masonry before work proceeds over. Masonry needs to be built tightly against the vertical section of the channel and a mortar joint added to the top of masonry, so that the loads from units above are spread evenly over the inner fl ange of the lintel. Composite lintels should be adequately propped during construction, at maximum 1.2 metre centres. Props should not be removed until the mortar has cured. 5 standard LeAF

Additional requirements for lintels supporting concrete floor units Check that the correct lintel has been installed. Minimum recommended lintel depth is 140mm in order to absorb the shock loading of concrete fl oor. Precast fl ooring units should be laid on a mortar bed across the whole wall width and should not be dragged over supports. important notes The loading fi gures published in the loadspan tables represent the Uniform Distributed Serviceable Load (UDL) in kn/m which can be supported by the lintel without the provision of structural brickwork/blockwork over. This is known as Independent Design. Lintel lengths shown greyed out within the loadspan table are available in longer lengths than the maximum clear span would normally allow. These longer lengths lintels should be used over a series of openings (with intermediate supports) NOT exceeding the maximum clear span and NOT simply supported at each end (i.e. all 65mm/70mm deep lintels must not clear span more than mm). % if in doubt please contact our technical department on ADvAnTAGes Easy to install and suitable for a variety of applications: internal partitions, external cavity walls, garages, over services. We offer a wide range of lintels from 100 x 65 through to 220 x 140 catering for every circumstance, with both Universal and Hi-Strength derivatives where required.
