The sia surface system

Customer service and support

As a metalworking professional in industry, in a workshop or in construction, or as a trading partner, you benefit from the expert advice and hands-on knowledge that our application engineers and abrasive experts bring to your workplace. This way, we ensure from the outset that you have the right sia Abrasives product to hand for any specific sanding application.

Surface analysis

No two surfaces are the same. We analyse your surface quality requirements as a whole, taking into account your processing steps both upstream and downstream of the abrasive process. We optimise your working process to maximise productivity and efficiency and, if necessary, look for alternative treatment methods.

Process optimisation

We help you select the optimal abrasives and tools, give you application recommendations and discuss with you the individual application steps in order to ensure maximum process stability and reproducible results.

Abrasives, tools and accessories

We offer you high-performance abrasives for all surface applications involving metallic materials. Our range of abrasive products is meaningfully complemented by a perfectly coordinated range of tools and accessories: abrasive spiral band holders and mandrels for die grinders, backing pads for angle grinders and rotary sanders, sanding grease and much more.

Training and documentation

At our Communication Centre in Frauenfeld, we hold courses and workshops for end users, retailers and specialist teachers as a forum for transferring know-how and sharing experience. We provide a wide range of documentation including comprehensive product information and detailed application recommendations. This gives you the means to ensure that you work with our products in a safe manner while guaranteeing that you end up with a perfect finish.
