Wedge Anchors and Expansion Anchors Manufacturer in China

Mechanical anchors for concrete, made to a clear range

WTFasteners — Hebei W.T Fasteners Co., Ltd. — catalogs mechanical anchors for concrete and masonry from its Handan factory. Wedge anchors in carbon steel, listed M6 through M30, are the torque-controlled workhorse: tighten the nut, the clip expands against the drilled hole, and the fixing is set. Expansion (sleeve) anchors and drop-in anchors cover lighter and flush-mount applications, with drop-in types listed M6 through M20. Carbon steel suits general construction; stainless steel options are listed for corrosive or outdoor environments — confirm the material against the exposure conditions when you inquire.

Because anchors are safety-relevant fixings, quotations start from the application: base material (cracked or non-cracked concrete, solid masonry), fixture thickness, required embedment and the load direction. Send these details and the catalog range is matched to the job rather than guessed from a diameter alone.

Concrete nails, clips and made-to-order specials

The same fixing family includes concrete nails, pipe clips, cable clips and special clips, listed to GB/T 27704 with customizable dimensions. Special clips are made to order: send a drawing or a sample and the dimensions, material and finish are confirmed before production. These items typically ship alongside anchor orders, letting distributors consolidate concrete-fixing lines into one factory shipment.

Where anchors are used

Typical applications include steel base plates and columns, racking and shelving, curtain-wall brackets, MEP supports, handrails, machinery hold-downs and formwork accessories. Project buyers usually order anchors together with the bolts, nuts and washers for the steel-to-concrete connection — a combination the factory quotes as one package. Carton or bulk packing, with labeling to the buyer’s requirement, is aligned before shipment.

Choosing between carbon steel and stainless steel usually comes down to exposure. Carbon steel anchors with zinc plating suit dry indoor environments and general construction, while stainless steel is the listed option for outdoor, coastal or chemical-exposed installations where corrosion would shorten service life. Embedment depth and edge distances should follow the fixing design: deeper embedment and correct spacing are what let the anchor develop its rated hold, and the factory confirms available lengths against the fixture thickness you report.

How to request a quotation

Send the anchor type, size, material, finish, quantity, packing requirement and destination port or country — plus the base material and fixture details for a correct match. For clips and specials, include a drawing or sample with dimensions and material. Reference photos are helpful when the exact style is unclear.
