Frequently Asked Questions (FAQ)
What materials are available for your wedge anchors?
We offer carbon steel wedge anchors (zinc plated or hot-dip galvanized) and stainless steel options including SS304 (A2-70) and SS316 (A4-80) for superior corrosion resistance.
Can wedge anchors be used in brick or hollow block masonry?
No, wedge anchors are torque-controlled expansion anchors specifically designed for solid concrete, cracked concrete, and uncracked concrete applications. They require solid material to expand properly.
How do I choose the correct length of a wedge anchor?
The total anchor length should equal the thickness of the material being fastened plus the minimum embedment depth requirement and the thickness of the nut and washer.
Do you support OEM branding and customized sizes?
Yes, we provide OEM services including custom sizes (metric and UNC threads), customized packaging, and private label/logo printing on boxes and cartons.
What is the standard lead time for bulk orders?
Our typical delivery lead time ranges from 10 to 25 days depending on the required specifications and order quantity, with shipment directly from Tianjin Port, China.
