German to English Tech/Engineering Engineering (general) Welding Spray

"Technische Sprays
für Industrie und Handwerk

Unser Service!

Qualität

zu ersetzen!"

From the cover of a little brochure for welding sprays and similar products.

Although "technical sprays" gets quite a few Google hits, an extremely high number of these seem to be on foreign Web sites, and I have a feeling that, as is so often the case with "technisch", it really means nothing here. "Technical sprays" just does not seem like natural English.

But I'd feel a little better if I could have my gut feeling confirmed. Can I just say "Sprays for industry and trade" and be done with it, or should I try to incorporate the "technisch" in somehow? TIA for your help.
