FAQ
Q1: Will 304 SS really never rust?
A1: 304 resists most salt-air; choose 316 for continuous immersion—polish yearly to keep the shine.
Q2: What holding force per buckle?
A2: 150 kgf (20 mm) to 350 kgf (38 mm); divide cargo load by number of buckles—safety factor 2:1.
Q3: Can I use 25 mm webbing in the 38 mm buckle?
A3: Yes—cam jaw adjusts to grip 20–38 mm; centred webbing gives max holding force.
Q4: Will the cam slip under vibration or shock load?
A4: No—serrated cam + spring preload grips tighter under load; tested 24 h vibration 50–500 Hz, zero slip.
Q5: Are spare 316 versions available?
A5: Yes—316 upgrade on request, MOQ 500 pcs, 25 % price adder.
Q6: Do you offer test certificates?
A6: Mill certificate for 304/316 SS, salt-spray report, and holding-force certificate supplied free on request.
