shot blasting

We collaborate

As our ambition is to always exceed our customer’s expectations, many of our abrasives such as all the Premium ranges has been developed with them. This customer-centric approach led us to keep a step ahead by anticipating the shot blasting market needs.

We collect

Circular economy is at the heart of our process, as 95% of our raw materials come from recycled scrap, collected within a 200km radius of our plants- ensuring that transporting the scrap does not negate the value of recycling it.

shot blasting

We melt

Scrap metal is melted, and alloys are added, then the liquid steel meets water jet to be atomized into small metal pellets. The smeltery dust rejected is used as a raw material in zinc production, iron oxide complements mined iron in blast furnaces, and slag is used in the sub-structure of new roads.

We transform

Offering a large range of products for all types of shot blasting operations, our abrasives are subject to thermal and mechanical treatments, giving them durability, shape and hardness suited for their purpose. Our compressors are equipped with heat recovery units to divert the heat generated to water or the plant itself. By using regenerative burners, we can conserve the heat produced and use it to reheat air in the furnace.

We inspect

Throughout the manufacturing process, a comprehensive inspection and control process is in place to ensure product quality, safety and environmental requirements. Since 1998, we are certified 9001 at our France plant, this quality management approach has been deployed to our 9 sites, which are now all accredited.

We supply

Our finished products are globally available, and dispatched whenever possible from the site that is closest to our clients.  We recently improved our packaging environmental impact including changing to a raw cardboard to avoid chemical treatment.

We improve

Both processes and products are endlessly evolving, all of Winoa’s actions are guided by the common-sense philosophy that unused energy is the best way to improve energy balance. The company’s pursuit of this approach has led it being ISO 50001 certified and can be seen even in its upstream energy procurement.
