1.The sleeve anchor allows it to anchor into concrete, bricks and blocks. The sleeve anchor works when you insert the sleeve anchor into the pre-drilled hole in the substrate and then turn the nut to pull the working end of the sleeve anchor up through the sleeve. The anchor is then expanded and firmly anchored into the concrete, brick or block. The anchors are available in galvanized and stainless steel. The sleeve anchor is fully assembled and ready to use. 2.Suitable for all kinds of steel structures, cable lines, brackets, gates, stairs, steel ladders and other building components that bear heavy loads of vibration, with reliable post-expansion function for earthquake resistance and durability.

1. Metal-frame anchor are mainly used for expansion anchors of doors and windows. The product is mainly composed of expansion tube screw taper nut.It can firmly fix machines, doors and windows, structural parts, equipment or various appliances on walls, bases or concrete foundations. 2. Advantage: Metal frame anchors have many advantages such as simple installation, firm fixation and convenient construction. 3. Application: Metal frame anchors are widely used in many industries, such as door and window installation, floor installation, fixing heavy objects, etc. In the decoration industry, they can be used to fix decoration materials.

1. How to use：When using the wedge anchor, you need to first use an impact electric drill to drill a hole of the corresponding size on the fixed body, then install the bolt and expansion tube into the hole, and tighten the nut to expand the bolt, expansion tube, mounting piece and fixed body into one. 2. Characteristics: Wedge Anchors do not have high requirements for the depth and cleanliness of concrete cavities and are easy to install. 3. Application: Wedge anchors are usually used in heavy-duty facilities and are suitable for concrete and dense natural stone, metal structures, metal profiles, base plates, support plates, brackets, railings, windows, curtain walls, machines, beams, girders, brackets, etc.

1. How to use: ① Drill a hole equal to the diameter of the anchor to the smallest size. ② Clear the hole and insert the anchor into the hole with a hammer ③ Tighten the nut to expand the anchor to fix the object 2. Application: ① Can be used for concrete, blocks, bricks, stones, steel structures, machines, doors, stairs, floors ② Can be used to repair the load of exterior walls or windows

1. Core type expansion bolt is a common connector, widely used in construction, bridge, mechanical equipment and other fields. It has the advantages of simple installation, high bearing capacity, good seismic performance and so on 2 Core expansion is mainly used in buildings to install suspended ceilings, walls, steel structures, wire trough pipe supports, air pipes, door and window frames and other places that need to be fixed. The expansion anchor has the characteristics of simple installation, reliable, strong bearing capacity and wide application range. At the same time, it can also adjust the distance between the fixed object and the substrate by tightening the screws.

1. Characteristic: The wall thickness of the expansion tube is thicker than that of ordinary expansion bolts of the same specifications;The expansion tube is longer than that of ordinary expansion bolts of the same specifications;Several more knurled grooves are added to the expansion tube to increase the tensile strength;The size of the screw head is larger than that of the ordinary expansion bolt head;The matching washer is a large washer. 2. Requirements: The drill bit required for drilling should be 6 sizes larger than the product size. 3. Application:Elevator expansion anchors are a type of fastener specially used for elevator installation. They are usually made of high-quality steel and have strong seismic resistance and gripping power.

1. Drop in Anchor is a kind of expansion bolt, Drop in Anchor thread is long and easy to install, usually used for heavy load facilities, so it is widely used, many industries can basically be used, generally play a fixed role, suitable for concrete and dense natural stone, metal structure, metal sheet, floor, support plate, bracket, railing and so on. 2. Widely used ‌ : the end of the pipe stretched into the hole of the tube plate by theDrop in Anchor rolls, resulting in continuous expansion of the inner wall of the tube, resulting in plastic deformation, the diameter of the tube increases, the tube head is completely fitted to the hole wall of the tube plate, and the tube plate is forced to produce elastic deformation. When the tube expander is removed, the elastic deformation of the tube plate wants to return to its original state, and the plastic deformation of the tube end can not be recovered, and the result is that the tube plate holds the tube end tightly, so as to achieve the purpose of sealing and firmly connecting the two.

1.Sleeve Anchor with Hook is a special threaded connecting piece used to fix pipe support, lift, bracket or equipment on the wall, floor and column. 2. Stainless steel expansion hook is widely used, mainly used in the integrated installation of multimedia classrooms, installation of manhole protective mesh, installation of power Wells, water Wells and other manhole cover protective mesh, curtain hanging and other fields. Lanterns can also be hung on the top, bird cages can also be used horizontally, and more manhole protection nets can be installed.

Drop in anchors are mainly used for situations where the embedded depth is shallow, by tightening the nut to expand the expansion tube and achieve fastening. This type of screw is suitable for concrete substrates, easy to install, and has high bearing capacity.

Hexagonal expansion stainless steel is widely used in steel structures, mechanical equipment, bridge engineering, construction engineering, power equipment, subway engineering and other fields. It is suitable for steel, brick walls, concrete and other materials with hollow or solid substrates, and has strong adaptability and reliability.

In construction engineering, the expansion screw of hexagonal flange sleeve significantly improves installation efficiency and simplifies the installation process. Its design is exquisite, easy to operate, and greatly saves construction time and cost.

Wedge anchors are mainly used for heavy-duty equipment such as pipe gallery hangers, seismic support hangers, glass exterior walls, elevator brackets, shelves, and railings. In addition, it is also suitable for concrete and dense natural stone, metal structures, metal profiles, bottom plates, support plates, brackets, machine beams, beams, brackets, etc.
