Product Description
Products Introduction
Mine anchor cable consists of spear head anchor cable body and external anchor head (also known as external anchor section, which is the part where the anchor cable can be tensioned and locked. Its types include anchor plug type, screw type, reinforced concrete cylinder anchor pier type, pier head anchor type and steel frame type).
Mine anchor cable is composed of steel strand, anchorage agent, tray, anchorage and other anchorage accessories, which can exert active pressure on surrounding rock through mechanical tensioning.
Producing Process:
The manufacturing process is divided into single wire manufacturing and stranded wire manufacturing. The (cold) wire drawing technology is used for the production of single wire. According to the different materials of the product, it can be high carbon steel wire rod, stainless steel wire rod or medium and low carbon steel wire rod. If galvanizing is required, electroplating or hot plating treatment shall be carried out on the single wire. In the process of strand manufacturing, a stranding machine is used to twist multiple steel wires into products. Prestressed steel strands also need to be stabilized continuously after forming. The final products are generally wrapped on the I-shaped wheel (reel) or completed as reel-less.
Application:
Galvanized steel strand usually refers to messenger wire, Guy wire, core wire or strength member, etc. It can also be used as ground wire/ground wire for overhead power transmission, barrier cable on both sides of highway or structural cable in building structure. The commonly used prestressed steel strand in prestressed steel strand is uncoated steel strand for prestressed concrete, and also galvanized, which is commonly used in bridges, buildings, water conservancy, energy and geotechnical engineering, and unbonded steel strand or monostrand, which is commonly used in floor and foundation engineering
Calculation of tensioning value of steel strand:
The tensioning force controlled by the construction design of prestressed tensioning of steel strand refers to the tension of steel strand in front of the anchor clamp after the completion of prestressed tensioning. Therefore, when calculating the theoretical elongation of steel strand prestress tensioning, the distance between the anchor points at both ends of the steel strand should be taken as the calculated length of the steel strand. However, the controlled tensioning force of the steel strand during prestress tensioning is controlled at the jack tool anchor. Therefore, for control and calculation purposes, the distance between the anchor points at both ends of the steel strand, plus the working length of the steel strand in the tensioning jack, is generally used, As the calculated length of the theoretical elongation of the prestressed tensioning of the steel strand. During the prestressed tensioning of steel strand, the exposed part of the steel strand is mostly wrapped by anchors and jacks. The tensioning elongation of the steel strand cannot be measured directly on the steel strand, so the tensioning elongation of the steel strand can only be calculated by measuring the piston stroke of the tensioning jack, but the anchor plug retraction during the whole process of the tensioning of the steel strand should also be reduced. The bearing capacity of the steel strand shall be 4-6 times of the total traction force

Company Profile
Company Introduction
Xinruyi Steel Group was built in year 2017 with registered capital of 30,000,000RMB, and we have been in the steel products industries for more than 10years. The group is located in Liaocheng City, next to capital of Shandong Province, and it enjoy good transportation environment of 3 hours to nearest port and 1 hour reaching the airport.
As it is well known to all, Liaocheng city is the biggest steel pipe base in North China, with this significant advantage on geography aspect, us company have developed into one modern international XINRUYI STEEL GROUP. Till now we have two production plants for steel pipes and plate series production and processing, and three warehouses for steel products. Our yearly production scale can be reach to 500,000tons, and our warehouse stocks is yearly above 20,000tons. So that we can meet all kinds of demands from different countries clients. Our salesmen are trained to get the best and professional skills on doing export trading dealing with various kinds of issues in the trading, which is a base that our buyers can have good buying experience. Till now we can supply the good quality products consisting of and not limit to the following, steel pipes, bars, rock bolts, guardrail composite pipe, guardrail board, color coated steel coils, galvanized coils, steel balls, steel chains, steel plates and steel bearing. Besides we can provides processing procedures for the steel products, like anti-rust protecting, cutting and chamfer, coupling, heat treating, bending, galvanizing, polishing, beveling, pickling, plastic spraying, CNC machining, and so on.
With efforts of Xinruyi People we have the pleasure to serve the clients from more than 20 countries and areas, We earned good reputations from the clients without any claim. We finally become good friends and intimate partners with them.
Looking forward, we get good confidence that we will expand our business scales to more countries and areas, and serve more people in the world. Because we always believe quality of the commodity is the life of company, stability is the essence of quality. Also the integrity in business will help bring the long term business relationship, so it is the code that one company can develop and survive.
Xinruyi Group is looking forward to the cooperation with you! We believe one time cooperation, friends forever!
(Xinruyi Steel Group Swear: we do not cheat any of our client, we only do business with good faith and honesty! Recent years especially in year 2021, lots of sellers of steels set up one international trading company, register Made-in-China VIP member, and make money by cheating clients.They are offering incredible low rate to attract clients and sending less weight goods to make money. )
(Xinruyi Steel Group Swear: Even if we do not get the order, we do not cheat even one client!)
(We give Made-in-China complain center as below: https://sourcing.made-in-china.com/complaint/)
