Frequently Asked Questions

Q: How do I choose the correct wedge anchor size for my project?

Selection depends on the required pull-out load and the thickness of the fixture. Refer to our detailed parameter table for diameter (M6-M24) and minimum embedment depth to ensure safety.

Q: What is the difference between Zinc Plating and HDG for fasteners?

Zinc plating is suitable for indoor or mildly corrosive environments. Hot Dip Galvanizing (HDG) provides a thicker protective layer, making it ideal for outdoor construction and marine environments.

Q: Can you provide customized lengths and diameters?

Yes, we welcome customized requests. Please provide your specific requirements regarding size, material, and surface treatment, and our engineering team will provide a tailored solution.

Q: What is the typical lead time for bulk fastener orders?

Standard bulk orders are typically finished within 20-25 working days. For customized samples, the turnaround time is approximately 7-10 working days.

Q: How are the anchors packaged for international shipping?

To ensure zero damage during transit, we use a secure system of Box + Carton + Pallet, designed for efficient handling at ports like Tianjin and Qingdao.

Q: What quality standards do your wedge anchors follow?

Our products are manufactured under the ISO9001:2008 quality management system and adhere to DIN, ANSI, ISO, and GB standards to guarantee global interoperability.
