Our customers manufacture high quality products for use in corrosive, cryogenic, high pressure or high temperature environments and require components in a wide range of materials and coatings. Deliveries are made on-time and customers frequently make use of our 24 Hour production and delivery service when an urgent item is required. For example when a competitor either fails to provide the high quality required or fails to deliver on time.
BNM also provides bar and cut sections for our customers own in-house machining operations when the minimum charges imposed by stock-holders is not economically feasible.
Our customers require total product confidence and traceability on their products. BNM’s quality and document control department ensures that this is maintained throughout production. The latest issues of all product and material specifications are used including Defence Standards and our product certification service is tailored towards the customer’s specific requirements.
