The standard adjustable steel support is a commonly used temporary support component in construction projects, and its weight is an important parameter related to on-site transportation, installation efficiency and structural stability. As a key index reflecting the structural characteristics of steel supports, the weight of standard adjustable steel support is not fixed, and is mainly affected by four core factors: adjustable length, tube diameter, tube thickness and material, among which Q195 steel is one of the most commonly used materials for standard adjustable steel supports.
The adjustable length range is the primary factor affecting the weight of standard adjustable steel support. Generally speaking, the longer the adjustable length range of the steel support, the more materials are needed for the inner and outer tubes, and the higher the overall weight. For example, standard adjustable steel supports with an adjustable length of 1.041 m to 1.829 m (commonly known as Size 0) have a relatively light weight, about 9.96 kg; those with an adjustable length of 2.7 m to 5.0 m have a heavier weight, up to 34.7 kg, which is related to the increase of tube length and the corresponding thickening of tube wall to ensure load-bearing capacity.
Tube specification, including outer tube diameter, inner tube diameter and tube thickness, is another key factor determining the weight of standard adjustable steel support. The common tube specifications of standard adjustable steel supports include 40/48 mm, 48/60 mm, 60/75 mm and 75.5/88.5 mm (inner tube/outer tube diameter), and the tube thickness is usually between 1.4 mm and 4.0 mm. Under the same length condition, the larger the tube diameter and the thicker the tube wall, the higher the weight. For example, the 60/48 mm specification (outer tube 60 mm, inner tube 48 mm) with a tube thickness of 1.8-3.0 mm has a weight of 11.5 kg to 17.79 kg when the adjustable length is 1.4 m to 3.5 m; while the 75/60 mm specification (outer tube 75 mm, inner tube 60 mm) with the same length range and a slightly thicker tube wall has a weight of 14.64 kg to 19.93 kg.
The material of the standard adjustable steel support also has a certain impact on its weight, and Q195 steel is widely used due to its appropriate mechanical properties and cost advantages. Q195 steel has a density of about 7.85 g/cm³, which is the same as that of ordinary carbon structural steel. The weight difference of steel supports made of Q195 steel and other carbon structural steels (such as Q235) under the same specification is small, and the weight difference is mainly reflected in the difference of tube thickness and structural design rather than the material itself.
In addition, the structural design of standard adjustable steel support, such as the type of nut (cup nut, cast nut), the size of base plate and the presence of auxiliary components, will also have a slight impact on the overall weight. For example, steel supports with cast nuts and larger base plates (120 mm×120 mm or 150 mm×150 mm) are slightly heavier than those with cup nuts and smaller base plates, but the weight difference is usually within 1-2 kg, which is negligible compared with the weight impact caused by length and tube specification.
It should be emphasized that the weight of standard adjustable steel support is closely related to its load-bearing capacity. In order to ensure sufficient load-bearing performance, the weight of steel support cannot be blindly reduced by reducing tube thickness or diameter. For example, heavy-duty standard adjustable steel supports used in large-load scenarios usually have a thicker tube wall and larger diameter, and their weight is relatively higher, ranging from 20 kg to 34.7 kg, which can better resist compression and bending and ensure construction safety.
In practical application, the weight of standard adjustable steel support is usually matched with its application scenario. Lightweight standard adjustable steel supports (9.96 kg-15 kg) are suitable for small-load support scenarios such as ordinary formwork; medium-weight ones (15 kg-25 kg) are applicable to general construction support; heavy-duty ones (25 kg-34.7 kg) are used in large-load scenarios such as bridge engineering and high-rise building formwork support, which can meet the diverse needs of construction sites while ensuring safety.
