Quality Assurance 

How do we maintain our high standards?

From the moment items arrive at our yard. We meticulously ‘check in’ each item, conducting thorough visual inspections to ensure:-

• The item is what we are expecting, in terms of size, shape and condition.
• We check for any damage that will affect the end finish.
• We inspect hot-dipped galvanised items to determine the extent of fettling required.

Should an item not pass our rigorous ‘check in’ process, it is immediately quarantined until we can confirm the details with our valued clients.

But our commitment to quality doesn’t stop there. At every stage of the item’s journey through our factory, we have robust checks and measures in place to maintain the highest quality finish.

Once an item has been processed we take meticulous care in packaging it for transport. Each item is packed with precision along with I.D paperwork to ensure it arrives at its final destination in perfect condition, reflecting our unwavering commitment to quality assurance.

To further demonstrate our dedication, we even have our own transportation service to ensure reliable and secure delivery to the site.

At NSP, we leave no stone unturned when it comes to quality assurance. Our unwavering attention to detail, rigorous inspections, and commitment to delivering flawless products are the cornerstones of our quality assurance process.

What tests do we perform?

The tests carried out depends on the item being coated and what we are doing to it, but here is a list of our most common tests.

Film thickness

Making sure we have an even coating of either zinc or powder coat is crucial for ensuring their quality and durability and any guarantee we might give, 25 year or 60 year. At our facility, we utilise the advanced Elcometer 456 tester, a cutting-edge tool that provides accurate film thickness results. This comprehensive test is carried out on HZS (Hot Zinc Spray) post blasting and powder-coated products to determine their thickness in microns, which is a critical factor for meeting industry standards and giving guarantees on our products.

Our testing process begins with measuring difficult areas, such as recesses, to ensure proper coating application. Random areas are also tested to verify that the correct levels of HZS and powder coating are maintained throughout the product. In case the coating levels fall below the required standards, our skilled technicians perform a recoat to ensure the product meets the desired specifications.

With our precise testing procedures and the use of advanced equipment like the Elcometer 456 tester, we ensure that our coated products meet the highest quality standards in the industry. Trust us for reliable and accurate coating thickness testing to ensure the durability and performance of your products.

Visual checks

Visual inspection is more than just looking; it also involves tactile examination to ensure the product has a smooth finish, free from lumps or blemishes. This inspection process starts during the preparation stage before the coating process begins.

Visual inspection is especially crucial for items that undergo shot blasting, and we adhere to the SA 2.5 / 3 standard.

After the coating is applied, it is essential to thoroughly inspect all the recesses to ensure adequate coverage and detect any areas with insufficient coating levels.
