Manufacturers’ ISO 9001 certificates are supplied where applicable and material test certificates are supplied with all materials.
We keep copies of test certificates of all supplied material on file indefinitely for future reference.
Our credo for quality material supply is that it must be fit for purpose and cost effective in the required application.
- Material purity
- Diameter tolerance
- Consistent mechanical properties
- Surface condition
- Surface finish
- Helix and cast of spring wire
- Even tension and layering of spools
It should be noted that not all of the above requirements are fully defined in most international specifications and should be agreed between buyer and seller at time of order.
To this end we work with our customers to provide the most appropriate specifications to ensure the best performance at the lowest total cost.
