Q: Which material grade should I choose for my application?
We offer W1 (galvanized steel) for standard indoor use, W2 (430 stainless steel band with a zinc-plated screw) for general automotive and industrial tasks, and W4 (304/316 full stainless steel) for high-corrosion environments like marine, chemical, or outdoor applications.
Q: What standards do these German-type hose clamps conform to?
Our German-type hose clamps are manufactured strictly according to the DIN 3017 standard, ensuring reliable dimension control, high torque performance, and universal compatibility.
Q: Can I customize the clamping range or band width?
Yes, while our standard band widths are 9mm and 12mm with a shown range of 25–40mm, we can customize clamping ranges from 8mm up to 240mm to meet your specific project requirements.
Q: Do you provide OEM/ODM services and product samples?
Yes, we offer complete OEM/ODM services including custom logo marking and packaging. Free sample testing is also available for bulk orders and large-scale projects.
