Our underground wells fence all by hand woven material is selected from the high intensity of high-strength wire and corrosion. Online there are 6 or 8 hooks, drill wells in the inner wall of the punch from the ground at 10 cm, can be installed. Nylon mesh tightly wrapped around the hook and folded several layers, increase the safety factor. Our five-star safety net of a subterranean well having a high anti-breaking strength, anti-aging, corrosion-resistant, safe, reliable, easy installation, etc., can be used underground 5--10 years. We do not with other manufacturers Hebei Five-Star than the price, and they are more than just quality because quality is the cornerstone of development and the fundamental, five-star people firmly believe that: Only the first productive force quality, is the business development and growth. Product quality is the lifeblood of enterprise development, is the most important factor in business survival. In our five-star Hebei people's minds. We produce a manhole every fence we put this network as a personal safety net, as a "life-saving net" because every one manhole safety net is carried by a fresh life, so we Hebei Five Star in every aspect of production, and strictly control product quality for inferior products hate them! Hebei star of every one of our network to go through a very rigorous process we Hebei Five-Star who deeply understand the "small manhole safety net, to protect the lives of big", that may seem simple, but in reality very important implications connotation. Our five-star safety net manhole products: 1. node - fixed - independent space - support gravity! ! 2. Our entire manhole using a rope fence is directly 3. Each rope is woven with three strands twist knot, bearing 4 star Yinjing stronger safety net adds special high-strength wire rope, black female, anti-aging agents, plasticizers, titanium dioxide and other polymer materials, through physical and chemical changes, disposable complex processing. Waterproof, anti-corrosion, not affected by the temperature and the environment. Corrosion: Materials and surroundings substance chemical reaction leading to the disintegration of the phenomenon. Corrosion: chromate, phosphate can be effectively suppressed. Example: shopping bags because they do not contain chromate, phosphate these additives, it is easier to degrade, decay. Product quality is a system that every one of our five-star safety net manhole to go through 12 steps before the factory, including the selection of raw materials, rope weaving, embalmed, net of production, gravity experiments, stereotypes, testing, packaging, etc. , each procedure is strict quality control standards to ensure the quality of each one manhole safety net must meet the technical standards of production. Hebei Five Star manhole underground fence well fall protection network covers safety net Ingredients: 1 PP: propylene as raw material by polymerization ---- ------ ---- melt spinning weaving and other processes in the system --- a high-strength fibers. 2 PP is divided into: carded, combed yarn, strand four formats, different formats determine their quality, but also determines how much cost. Carded - only a simple primary of textiles. Combing - use a special process in order, no impurities, fiber and more straight and smooth. Yarn - textile made directly, a twist that is scattered, commonly known as "yarn." Strands - must consist of more than two textile yarns together referred to as "line." So, like carded yarn made of textile made of polypropylene rope, the price is relatively cheap, the market most of manhole safety net is to use this type of woven polypropylene rope, of course, low cost. The Hebei Five Star Yinjing fence, using a special combing process, multi-strand wire twisted into a rope. And each manhole safety net cord have three ropes woven combination, with more tension and loading capacity, quality and particularly stable. Hebei Five Star manhole underground well fall protection safety net safety net net covers Twist: Twist determine the strength of the rope, rational decisions strength rope twist. What is the twist? 360 degrees around the axis of rotation is a twist. By twist, the friction coefficient between the fibers increases, the resistance increased, so that the strong increase tension and multiple lines. According to our scientific and technical personnel Hebei five-star 370 times after the trial: 6 twist equal to 6-fold increase in the strength and tension, a polypropylene rope sixfold increase in strength and tension. Hebei Five Star Yinjing fence rope is composed of three strands woven combination. So, Hebei Five Star Yinjing fence rope used increased by 18 times more than other manufacturers of strength and loading capacity. Reasonable twist determines the quality of rope, rope quality determines the quality of manhole protective net. So, we Hebei Five Star Yinjing safety net with high strength, high elasticity, stretching more than appropriate, good gloss, supple feel. We Hebei five-star safety net Yinjing used rope used: the cable and dock large ships, containers, steel mills and other equipment with a woven sling. Hebei Five Star manhole underground well fall protection safety net safety net net covers stainless steel expansion hook: many kinds of varieties of stainless steel, the price is uneven. From the stainless steel model is divided from 200-620, covering a wide range of models. We Hebei star of stainless steel expansion hook, using 304 stainless steel. 304 stainless steel carbon content of less than or equal to 0.08, the nickel content greater than 8% -10.5%; 201 stainless steel nickel content of only 4%, and even content of less than 0.6% manganese to replace part or all of the nickel, called " austenitic stainless steel ", commonly known as" imitation stainless steel ", No. 201 stainless steel than 304 damaged speeds up to 10 ---- 100 times. Therefore, the comparison of the above data, the quality of the product determines the cost of the product. The low-quality stainless steel is difficult to achieve security, stability, no rust effect. Hebei Five Star Electric Equipment Co., Ltd. manhole safety net has passed quality inspection in Hebei Province Special Equipment Supervision and Inspection Institute and Hebei labor protection products quality supervision and inspection, testing standards based on national standards GB5725-2009, the company is the country's safety net Yinjing the sole basis for national standards for the production of special protection product quality, quality, test report No. 0016 Hebei Quality Supervision literacy word. Hebei Five Star Electric Equipment Co., Ltd. in the first successful development of our country for municipal wells, electricity well, communication wells, water wells, inspection wells, gas wells, water wells specially designed manhole protection safety net, can effectively reduce the frequency of accidents. Hebei Five Star Electric Equipment Co., Ltd. production of patented products - silo protective net product quality has been 100 million underwritten by China Ping An Insurance Company! Hebei five-star safety net even in 3 standard radiation whole of Shanxi to the whole of China. ┏┯┓ ┠ exhaust ┨ Contact: Liu Huan Cheng ┨ ┠ fixed: 0311-80934260 ┠ as ┨ phone: 18332221409 ┠ You ┨QQ: 1906778434 ┠ service ┨ company website:?
