GEC Anderson has launched a new website for specifiers of stainless steel. The site includes product data, frequently asked questions, CAD downloads and technical details, plus images of the company's worktops, sinks, bowls, cabinets, shelving and sanitary appliances.

Callenders Interactive Roofing Centre features the "SpecBuilder" to help in the specification of roof coverings. Users complete a series of questions covering building use, the type of roof deck and the type and length of guarantee. A specification is then produced, along with a diagram showing the relevant detail. These can be downloaded for future reference.

Lafarge Plasterboard's specification tool Select 2 is available on the company's site. The system allows users to input drywall requirements such as partition height, fire and sound ratings and then automatically displays the most appropriate options from the company's product range. These can then be sorted in a number of ways, depending on user preference.

Lighting specialist Erco has developed a website detailing its products, projects and lighting design tools. The site includes a luminaire database containing light simulation and calculation programs, an online catalogue and the company's encyclopedia of light. It also allows users to explore the numerous uses of lighting control in architecture using interactive animation.
