Steel Wedge Anchor Plated by yellow zinc plating, produced by the carbon steel 4.8 gr.-8.8 gr. heat treatment. The clip is formed around anchor,assuring full expansion for dependable,superior holding power. Expanding clip will not fall of twist in the hole.
Concrete wedge anchor can be used as expansion bolt. The types of expansion anchors include pre-assembled matching cylinders and threaded wedge expansion anchors or it is called through bolt anchor . Wedge anchors are of carbon steel and stainless steel construction with different head types and can be used on cracked and uncracked concrete, block, brick and stone surfaces.
The key point of the design of masonry wedge anchor to realize the anchoring function is that the conical rod body at the lower end is wrapped by an expansion clip. When it is fastened by the nut, it will gradually slide down and expand under the action of the friction force of the tunnel wall, so as to achieve the purpose of expansion.
Wedge anchors are available in galvanized carbon steel construction with external hex nut and washer styles and in a variety of diameters from M6-1/4 inch to M20-3/4 inch.
They can be customized according to specifications and wedge anchors are produced for OEM markets. Wedge anchors are usually used in bridge decks, wharves, subways, concrete construction sites, walls or floors. They are available in galvanized steel, hot dip galvanized coating and 304 and 316 stainless steel grades as the different installation application.
Wedge anchors are made of a variety of different types of materials and coatings. There are two kinds of carbon steel wedge anchor bolts, galvanized or hot-dip galvanized. Stainless steel wedge anchor bolt is made of 303/304 or 316 stainless steel. From the use point of view, carbon steel galvanized wedge anchor bolt is suitable for dry indoor application without moisture. Hot dip galvanized wedge anchor bolt can be used in outdoor humid environment. 303 / 304 stainless steel is suitable for humid indoor and outdoor environment. 316 stainless steel is used in immersion liquid environment which is essentially corrosive or indoor environment with special installation requirements. In recent years, with the continuous improvement of environmental protection requirements, the spray Dacromet process on the surface of carbon steel tapered bolts has been emerging, which is more suitable for the environment with high salt concentration and humidity. Its anti-corrosion and anti rust performance is better than that of hot-dip galvanizing, and the environmental protection performance is also higher.
