Pre-embedded anchor bolts: These are directly embedded during concrete pouring and come in straight hook, L-shaped, U-shaped, and welded plate types. They offer strong installation stability and are suitable for heavy-duty equipment (such as machine tools and generators). The pre-embedding location and depth must be planned in advance.
Post-installed anchor bolts: These are fixed after concrete hardening by drilling and applying adhesive (chemical anchors). Installation is flexible and suitable for later equipment additions and foundation modifications. Drilling accuracy and adhesive curing time must be controlled.
Expansion bolts: These use expansion tubes to spread and rub against the concrete hole wall for fixation. Installation is convenient and suitable for light to medium-duty equipment (such as small motors and supports). They are not suitable for scenarios with strong vibrations or high precision requirements.
We understand that wholesalers need a stable and reliable supply, therefore we solemnly promise the following for every order of galvanized anchors:
First, Quality Guarantee: If any galvanized anchor does not meet DIN 5299/ASTM F1554 standards-whether due to insufficient galvanization, dimensional deviations, or inadequate strength-we will replace it free of charge. Furthermore, each batch has a complete batch traceability report.
Second, Fast Delivery: We maintain a year-round stock of commonly used sizes (M12/M16/M20, lengths 200mm/300mm/400mm) of galvanized anchors.
Third, Production Transparency: We can provide capacity reports and factory audit videos upon request, allowing you to demonstrate our production capabilities to your customers.
Fourth, 24/7 Support: If you require assistance with technical specifications, order updates, or bolt and nut/washer matching, they will respond within one hour.
We are your trusted supplier. If you are a buyer who needs our products or are interested in them, please contact us:
