1.Brief Introduction Ground screw is a large screw, using special machines will drill into the bottom, can be achieved with the concrete base the same strength and tensile force. The cost of this method is more lower than the traditional concrete method, and the disintegration of easy to remove, and can be repeated use. Therefore, now the solar power generation equipment are used this ground screw to stability the foundation. Keystone Ground Screw is specially developed for the maximum flexibility in designing for both residential and commercial solar mounting system, which can be applied to various soil conditions and/or can be customized according to Clients specific requirements. 2.Advantages 1) Quality Guaranteed: Treated with a layer of zinc, ground screw enjoys a longer life span with better corrosion resistance. 2) Versatile mechanical innovation: Unique structural design ensures a much better pull-out and load bearing capacity. 3) Application is wide that can be used in all types of soil and all type of structures. 4) Easy Installation,remove and relocate: Highly pre-assembled structures with minimal components and the adaption of hydraulic pile hammer ensure a quicker and easier installation with less labour cost, which takes 2 minutes on average only to ram a ground screw. 5) Environmental- friendly application: Compared with concrete bases, ground screws can be fully recyclable and cost effective, while produce little waste and can easily be removed. 3. Applications Ground screws when used directly into the inner of earth¡ê¬without digging, backfilling process, does not destroy the surface. On the grass, planting belt also easy construction, no need of transplant trees, flowers etc.. 1) Timber construction 2) Solar Power Systems 3) City and Parks 4) Fencing Systems 5) Road and Traffic 6) Sheds and Containers 7) Flag Poles and Marks 8) Garden and Leisure 9) Boards and Banners 10) Event Structures 1800x1000x1200mm

china coal 0001 Introduction of Hydraulic Spiral Screw Pile Driver 1. Hydraulic Spiral Screw Pile Driver using a new hydraulic technology, low consumption, large rotary torque,move the hole and shift the position is convenient. 2. The drilling rig structure is compact, it has a telescopic compensation function when promoting the slide carriage, the slide carriage supported on the ground when drilling, the drilling stability is very good. 3.The drilling rig is mainly used for piling anchoring, well, photovoltaic solar rotating pile and water conservancy, power plants, open-air mining, road construction and other stonework blast hole drilling and so on.

Fasteners with a tapered shank (self-tapping screws) chipboard screw & particle board screw Similar to a drywall screw except that it has a thinner shank and provides better resistance to pull-out in particle board, while offset against a lower shear strength. The threads on particle board screws are asymmetrical. concrete screw& Tapcons & masonry screw & confast screw & blue screw & self-tapping screw & Titen A stainless or carbon steel screw for fastening wood, metal, or other materials into concrete or masonry. Concrete screws are commonly blue in color, with or without corrosion coating. They may either have a Phillips flat head or a slotted hex washer head. Heads sizes range from 0.1875 to 0.375 in (4.763 to 9.525 mm) and lengths from 1.25 to 5 in (32 to 127 mm). Typically an installer uses a hammer drill to make a pilot hole for each concrete screw. deck screw Similar to drywall screw except that it has improved corrosion resistance and is generally supplied in a larger gauge. Most deck screws have a type-17 (auger type) thread cutting tip for installation into decking materials. They have bugle heads that allows the screw to depress the wood surface without breaking it. double ended screw & dowel screw & hanger bolt Similar to a wood screw but with two pointed ends and no head, used for making hidden joints between two pieces of wood. A hanger bolt has wood screw threads on one end and machine threads on the other. A hanger bolt is used when it is necessary to fasten a metal part to a wood surface. drive screw & hammer drive screw Chiefly used for attaching manufacturers data plates to equipment. Smooth round or mushroom headed with a multi-start thread on the shank, beneath which is reduced diameter shank that acts as a pilot. The screw is fastened by hitting the head with a hammer and is not intended for removal drywall screw Specialized screw with a bugle head that is designed to attach drywall to wood or metal studs, however it is a versatile construction fastener with many uses. The diameter of drywall screw threads is larger than the grip diameter. eye screw & screw eye & vine eye Screw with a looped head. Larger ones are sometimes called lag eye screws. Designed to be used as attachment point, particularly for something that is hung from it. A vine eye (in the UK at least) is similar to a screw eye, except that it has a proportionally longer shank and smaller looped head. As the term suggests vine eyes are often used for attaching wire lines across the surface of buildings so that climbing plants can attach themselves.

This company produces the SJZS series cone-shape double screw rodplastic extruding machine, has forces to squeeze out, high grade, thecompatibility broad, the life long, the shear rate small, the materialis not easy to decompose, to mix builds up the plasticizing to be good, the powder material directly takes shape and so on the characteristic, provides the direct current velocity modulation, the temperature automatic control, installment and so on vacuum exhaust. Is suitable to product the and so on tube, board, different shapematerial production.
