Hot dip galvanized angle steel is also known as hot-dip galvanized angle steel or hot-dip galvanized angle steel. It is to immerse the derusted angle steel in a molten zinc solution at around 500 ºC, so that a zinc layer is attached to the surface of the angle steel, thus achieving the purpose of corrosion prevention. It is suitable for various strong corrosive environments such as acid and alkali mist. The process flow of hot-dip galvanized angle steel: angle steel pickling - water washing - immersion plating solvent - drying preheating - hanging plating - cooling - passivation - cleaning - polishing - completion of hot-dip galvanizing. The galvanized layer thickness of hot-dip galvanized angle steel is uniform, up to 30-50um, with good reliability. The galvanized layer is metallurgical bonded with the steel, becoming a part of the steel surface. Therefore, the coating durability of hot-dip galvanized angle steel is relatively reliable. It is widely used in power towers, communication towers, railways, highway protection, street light poles, marine components, building steel structural components, substation ancillary facilities, light industry, etc.
| Angle steel | ||||||||
| Angle steel refers to a solid strip of steel with a circular cross-section, and its specifications are expressed in millimeters of diameter. For example, "50" represents an angle steel with a diameter of 50 millimeters. | ||||||||
| Characteristics of angle steel | 1, The angular structure gives it good support strength. 2, Under the same support strength, the weight of angle steel is lighter, consumes less materials, and saves costs. 3, Construction is more flexible and takes up less space. |
|||||||
| The purpose of angle steel | Angle steel, due to its high cost-effectiveness, is widely used in various fields such as housing construction, bridges, tunnels, power towers, ships, brackets, steel structures, etc., playing a role in supporting or fixing structures. | |||||||
| Type and specification of angle steel | ||||||||
| It is mainly divided into two types: equal edge angle steel and unequal edge angle steel, among which unequal edge angle steel can be divided into two types: unequal edge equal thickness and unequal edge unequal thickness. | ||||||||
| The specifications of angle steel are represented by the dimensions of edge length and edge thickness. At present, the specification of domestic angle steel is 2-20, with the number of centimeters of the side length as the number. The same size angle steel often has 2-7 different side thicknesses. Imported angle steel shall be marked with the actual dimensions and edge thickness on both sides, and relevant standards shall be indicated. Generally, those with a side length of 12.5cm or more are large angle steels, those between 12.5cm and 5cm are medium angle steels, and those with a side length of 5cm or less are small angle steels. | ||||||||
| Appearance quality of angle steel | ||||||||
| The surface quality of angle steel is specified in the standard, and it is generally required that there should be no harmful defects in use, such as layering, scarring, cracks, etc. | ||||||||
| The allowable range of geometric deviation of angle steel is also specified in the standard, generally including bending degree, edge width, edge thickness, top angle, theoretical weight, etc., and it is stipulated that the angle steel shall not have significant torsion. | ||||||||
| Chemical composition of angle steel | 1) Composition indicators: The chemical composition of angle steel belongs to the rolled steel series for general structural purposes, and the main verification indicators are C, Mn, P, and S. According to different grades, the content varies, with a rough range of C<0.22%, Mn: 0.30-0.65%, P<0.060%, and S<0.060%. (2) Inspection method: When testing the above chemical components, commonly used standard inspection methods include GB223, JISG1211-1215, BS1837, BS Manual 19 ГОСТ 22536, etc. |
|||||||
| Mechanical properties of angle steel | (1) Inspection method: Tensile test method. The commonly used standard inspection methods include GB/T228-87, JISZ2201, JISZ2241, ASTMA370 ГОСТ 1497, BS18, DIN50145, etc.; Bending test method. The commonly used standard inspection methods include GB/T232-88, JISZ2204, JISZ2248, ASTME290 ГОСТ 14019, DIN50111, etc. (2) Performance indicators: The main inspection items for evaluating the performance of angle steel are tensile test and bending test. The indicators include yield point, tensile strength, elongation, and bending qualification. |
