Introduction warning signs pile, also known as piles, piles logo, staking, commonly used in electric power, telecommunications, gas, water, rail and buried pipeline route signs. Used outdoors, green belt, bushes, top side pipe pipeline route instructions. Category 1, the use is divided into: cable signs pile, oil and gas mark piles, piles communication flag, cable signs pile, water signs pile, pile railroad signs, highway mileage piles. Mainly based on the product's use and print content above classification. 2, according to the material can be divided into: Cement signs pile, steel signs pile, pile composite mark. Composites signs pile is divided into: Magnesite signs pile, fiberglass signs pile, resin Gaza signs pile, resin signs pile. (1) Cement signs pile: the material is concrete, part of the internal reinforcement. Traditional materials, writing easily blurred, the need for regular maintenance. Not acid, the material is heavy, inconvenient transportation and installation. (2) Signs pile Magnesite: Magnesite signs pile magnesite cement is modified cementitious materials, supplemented by the necessary filler, then reinforced and made of reinforced material, is a new sign of the pile is A good substitute for cement, steel and resin signs pile, which can effectively solve the underground facilities Waduan problems, mainly used for signs and warning signs, electricity, telecommunications, gas, water, railways and other pipeline path channel. Now widely used to direct the downtown area, scenic areas, green belts, bushes and top sides of the tube pipeline route, a huge market prospects. Specific advantages are as follows: Magnesite signs pile characteristics: a high strength, hardness, impact resistance, wear resistance, high temperature resistance, corrosion resistance, long service life of 30 years; b production process non-toxic, safe environment;. c, looks beautiful, the product can be made into a variety of colors, fonts clear pattern, obvious warning and beautify the urban environment;.. d light weight, easy transportation and installation, can greatly reduce the labor force and reduce labor intensity;. e anti-theft, This material has no recycling value, anti-theft alarm. [1] (3) steel signs pile: the material is (PVC, polyvinyl chloride). Material lightweight, flexible, acid corrosion resistance, good anti-aging properties. Easy installation and transportation. (4) Fiberglass signs pile: high temperature repression. Impact resistance, wear resistance, high temperature resistance, corrosion resistance, can be resistant to water, gasoline, alcohol, salt electrolysis, acetic acid, hydrochloric acid, sodium and potassium compounds, urine, asphalt, for a variety of acid soils. Life of up to 30 years. Content using screen printing technology, warning effect, and no maintenance. Light weight, easy transportation and installation. No recycling value, natural anti-theft. [2] (5) Resin signs pile Gaza: Gaza resin material. Hot die forming, impact resistance, wear resistance, high temperature resistance, corrosion resistance, service life of up to 50 years. Surface using intaglio process clear and beautiful font pattern. Anti-theft. Is a sign both fiberglass and concrete signs pile pile product advantages. (6) Resin signs pile: pure resin production, the cost is very high, generally not used. 3, specification steel / pvc signs pile: 100 * 100 * 100mm signs pile wall thickness 3-4mm 120 * 120 * 800mm signs pile wall thickness 3-4mm 150 * 150 * 800mm signs pile wall thickness 3-4mm 100 * 100 * 800mm Signs pile wall thickness of 3-4mm 100 * 100 * 800mm thickness of 3-4mm signs pile composite coating / engraved signs pile: 120 * 120 * 800mm signs pile wall thickness of 4-5mm 120 * 120 * 1000mm signs pile wall thickness 4- 5mm 150 * 150 * 1000mm signs pile wall thickness of 4-5mm Fiberglass signs pile: 120 * 120 * 1200mm signs pile wall thickness of 4-5mm 80 * 80 * 1000mm signs pile wall thickness of 4-5mm 100 * 100 * 1000mm signs pile wall thickness 4-5mm 150 * 150 * 1000mm signs pile wall thickness of 4-5mm 120 * 120 * 1000mm thickness of 4-5mm triangle logo signs pile pile: 100 * 100 * 1000mm signs pile wall thickness of 4-5mm 120 * 120 * 1200mm signs pile wall thickness of 4-5mm 150 * 150 * 1500mm signs pile wall thickness of 4-5mm 280 * 280 * 2800mm signs pile wall thickness of 4-5mm pipe signs pile: 100mm diameter concrete signs pile: 120 * 120 * 800mm 4, characteristic signs pile As a marking device. It plays an important role in pointing the danger zone or zones. It generally has the following characteristics: a bright appearance, allowing people to pay attention to the timely discovery. 2 changeable styles, can be used in any environment. 3 Good material, you can easily transport and installation, and has a long service life. 4 has a certain anti-theft capacity.
