When coiling galvanized steel wire on wooden reels, the selection of the size of the wooden reel needs to comprehensively consider factors such as the specifications, length, weight, usage scenarios, and equipment matching of the galvanized steel wire. The following are the specific considerations:
**Diameter**: Generally speaking, the larger the diameter of the steel wire, the larger the diameter of the required wooden reel should be to ensure that the bending radius of the steel wire is appropriate during coiling, and to avoid stress concentration caused by excessive bending of the steel wire, which may affect the performance of the steel wire. For example, for relatively thin galvanized steel wires with a diameter of 1-3mm, a wooden reel with a diameter of 600-800mm can be selected; for medium-thick steel wires with a diameter of 3-6mm, the diameter of the wooden reel can be between 800-1200mm; for thick steel wires with a diameter greater than 6mm, a wooden reel with a diameter of more than 1200mm may be required.
**Strength**: High-strength galvanized steel wire require greater supporting force during coiling, and it is also necessary to select a wooden reel with appropriate size and sufficient strength to prevent the wooden reel from deforming or being damaged due to excessive tension during the coiling process.
**Length**: Longer galvanized steel wires require larger wooden reels to accommodate them, in order to reduce the number of coiling layers and lower the extrusion and friction between the steel wires caused by multi-layer coiling. For instance, for steel wires with a length of less than 1000 meters, a wooden reel with a smaller diameter can be selected; for steel wires with a length of 1000-5000 meters, a wooden reel with a diameter of 800-1500mm is advisable; for long steel wires with a length of more than 5000 meters, a large wooden reel with a diameter of more than 1500mm is required.
**Weight**: Select an appropriate size according to the load-bearing capacity of the wooden reel. Generally, the load-bearing capacity of a small wooden reel is 1-2 tons, that of a medium-sized wooden reel can be 2-5 tons, and that of a large wooden reel can be more than 5 tons. In practical applications, it is necessary to ensure that the load-bearing capacity of the wooden reel is slightly greater than the total weight of the steel wire to ensure safety and stability.
**Usage Scenarios**: If the galvanized steel wire is mainly used in large-scale engineering sites such as buildings and bridges, usually larger-sized wooden reels are required to facilitate hoisting and installation. For some small processing workshops or maintenance sites, a smaller-sized wooden reel can be selected according to the actual operating space and requirements, which is convenient for handling and use.
**Equipment Matching**: It is necessary to consider the matching degree with the wire pay-off equipment and wire take-up equipment. The dimensions such as the diameter, shaft diameter, and width of the wooden reel should be adapted to the parameters of the equipment to ensure that the wire pay-off and wire take-up processes can proceed smoothly and avoid situations such as jamming or instability.
**Transportation and Storage**: If the coiled galvanized steel wire needs to be transported over long distances or stored, the impact of the size of the wooden reel on the transportation means and storage space should be considered. Smaller-sized wooden reels are relatively more convenient for transportation and storage, which can save space and transportation costs, but the coiling capacity of the steel wire also needs to be balanced.
**Cost Factor**: The larger the size of the wooden reel, the higher the production cost and material cost usually are. On the premise of meeting the usage requirements, the cost factor should be comprehensively considered, and a wooden reel with high cost performance should be selected.
