STRUTIMBConfidence in using a STA member companyBuildinThe Structural Timber Association (STA) represents the vast majority of the structural timber industry, with an extensive membership covering a range of businesses engagedin the delivery of structural timber buildings. This includes the materials supply chain, engineers, designers, manufacturers, erector/installers and associated firms providingsupport services, such as legal and insurance businesses.The STA offers differing levels of membership, each requiring defined levels of quality in the way our members undertake their work. However, the extensive range ofmembership businesses means that the specific quality requirements differ for each type of member and customer activity.Choosing to work with a STA member company gives you the confidence that no matter what service they are providing, they are meeting the STA’s membership criteria.They will also have the necessary accreditation to comply with the Construction Products Regulations (CPR) and CE marking, where applicable.There is always a commercial decision to adopt increasingly recognised accreditations and standards. The STA guides its members to achieve the highest levels of quality andperformance across a range of industry standards; see additional information provided in this document.STA membership levelsThe STA has established three levels of membership; Gold, Silver and Bronze. The levels of membership are designed to recognise the differing levels of standards held byour members.It is important to point out that depending on the nature of a company’s business, a Bronze or Silver member maybe the most appropriate company for your project requirement.2STA MEMBERSHIP AND QUALITY STANDARDS

STRUTIMBMembership types and definitionsBuildinWe split our membership types as follows (each with different quality standards) as listed below.Key on terminology:1.Element is the component part that makes up a product2.Product is the building system or assembled part that will form the building systemStructural timber building system (STBS) membersA STBS member is a company that has been contracted to provide a building system to the customer. The customer may be the building end-user, a developer, a maincontractor, a sub-contractor or a self-builder. The contract can be to either supply a kit of elements or to supply and construct the elements on the site.The scope of elements includes any of the following: assembled walls, floors or roof panels. Loose materials, joists, rafters etc. may also be supplied through the structuraltimber building system member. See Appendix 1 for further details of works typically covered by our STBS members.Product supply chain membersThis is a STA member providing materials and component parts to be used in the manufacture of structural timber building systems/elements for site assembly. Examples ofthis type of member is a supplier of joists, boards, fasteners, insulation, membranes etc.Product supply chain membership also includes businesses that manufacture components like truss rafter roofs and open web joists, Glulam beams, I-joists and steel framesto be used by others. It also encompasses structural products such as SIPs and CLT panels that go on to be processed by others into wall, floor and roof elements.Erector/installer membersBusinesses that assemble elements and products on-site to form the building shell which are designed and supplied by others.Designers, engineers and consultants, plus professional service supplymembersBusinesses that produce fabrication drawings and/or engineering calculations for the elements and building structural system, including energy performance, acoustic, fire, safetyand acoustic services. Service supply chain businesses provide ancillary support roles to the timber industry such as solicitors, construction plant suppliers and insurance brokers.CE markingAs a customer of an STA manufacturer – a developer, specifier, contractor or self-builder - you are required by European law, called the Construction Products Regulation(CPR), to purchase CE (Conformité Européenne) marked products, when the product can be assessed by what is called a Harmonised European Standard. Not all productshave harmonised standards, but for structural timber building systems most of the products used do. Products like fasteners, timber boards, timber, joists, CLT, Glulam andplated trussed rafters are all eligible for CE marking.STA members are therefore legally bound to provide CE marked building products and systems where appropriate - and naturally the STA has made CE marking of the products(where applicable) a condition of membership. We provide our members with advice on what products and systems have a harmonised standard (hEN). We also offer ourmembers guidance on the voluntary CE marking route for products where a European Assessment Document (EAD) can be achieved.STA members are regularly updated on the CE marking of products and you can be assured they can access the latest information to enable you, as their customer, to complywith the CPR.3STA MEMBERSHIP AND QUALITY STANDARDS

STRUTIMBMinimum quality standard requirementsBuildinSTBS membersEntry level membership to the STA for STBS members is Assure Bronze. To achieve this, our member will be asked to register with the STA and to state that they only use CEmarked products (materials and components), where appropriate. All new members will be assessed by a STA consultant to review their in-house quality standard.Assure Silver membership requires STA members to undertake an ISO 9001 audit of their factory and product production. There is also and option for STBS members tohave third party product performance design checks and reports.Assure Gold level members must have an audit of their management systems and the performance of their building system (or element). See table on page 4 for examplesof approved audits.Audit of management systems andbuilding system performanceAudit of factory andproduct productionIn-house quality standards CE marked productsProduct supply chainEntry level membership for product supply members is Assure Bronze.Assure Silver membership requires the STA member to hold an appropriate ISO 9001 certificate.Assure Gold level members are required to have an ISO 9001 and also a product performance certification appropriate to their product e.g. CE marking certification, BBA,BM TRADA Q Mark.ISO 9001 product performancecertification (i.e. CE marking, BBA)ISO 9001In-house quality standards8STA MEMBERSHIP AND QUALITY STANDARDS
