Zhenkai Tools/Staple guns (GS-Mark)
SG SERIES · GS-MARK

Staple guns that
carry a number you
can look up.

Our staple guns were type-tested by TÜV Rheinland and carry the GS-Mark. We give you the approval number rather than a logo, because a logo on a webpage proves nothing — a number in the issuer's database does.

What the GS-Mark is — and is not

GS stands for Geprüfte Sicherheit, "tested safety". It is a German product-safety mark issued by an authorised body — in our case TÜV Rheinland — after the product has been type-tested. It is not an ISO certificate, and it is not something a manufacturer can declare on its own letterhead: the certificate sits in the issuer's database with a number attached.

For a European buyer the practical difference is this: a supplier who can quote a test-mark number is a supplier whose product has been through someone else's laboratory. One who cannot is asking you to take the word of the factory that made it.

Why we put the number on the page instead of a badge. Any printer can put a GS logo on a website. The approval number 50571636 can be checked in TÜV Rheinland's database under our company name — go and check it before you ask us for a price.

QUESTIONS BUYERS ASK

Answers, straight.

Do your staple guns carry the GS-Mark?

Selected models do: WJ-B3, WJ-B8, WJ-B11, WJ-B15 and WJ-B18, under GS approval number 50571636, tested by TÜV Rheinland. You can look the approval up in Certipedia under our company name. We publish the number rather than a logo because a number can be checked and a logo cannot.

Can you put our brand on the staple gun?

Yes. Bodies, pad printing and packing are done on floor 3 of our own building, so branding is a specification we control rather than something we subcontract.

What is the sample lead time?

7–10 days. Bulk production starts only after your own QC has signed off on the sample — we do not start a run on a deposit alone.
