All SCC building wire designs use constructions covered by BS:6004 and SASO 55 standards. However that SCC can also supply a range of alternative designs to meet more specialised customer needs including enhanced fire performance and added environmental protection. Building wires can also be supplied with alternative sheathing materials and colours, or can be made to individual customer specifications or other recognised standards. In particular, wires can be manufactured to meet specific requirements for the elimination of smoke and toxic gases using low smoke and non-halogen emitting materials.
