The hole design of galvanized angle is a key factor affecting its installation convenience. From the number of holes, layout to shape details, they are closely related to installation efficiency and operation difficulty. Reasonable hole design can simplify the installation process, lower the construction threshold, and ensure the stability of the connection.
The number of holes directly determines the convenience of installation and the strength of the connection. Although fewer holes can reduce the steps of drilling and screw fixing and save installation time, it may cause the connection to be not firm enough and easy to loosen when subjected to external force. Too many holes will increase the complexity of installation and extend the construction time. The appropriate number of holes needs to take into account both installation efficiency and structural stability. For example, in the assembly of light furniture, galvanized angles with 2-4 holes are usually used, which can ensure the strength of the connection and facilitate quick installation; in the connection of doors, windows or building structures with larger load-bearing capacity, angle codes with 4-6 holes are used to disperse the force through multiple fixing points to ensure stability. At the same time, the increase in the number of holes does not excessively affect the convenience of installation.
The layout of the holes has an important impact on the convenience of installation. Symmetrically distributed holes are convenient for construction workers to quickly locate and operate, without repeatedly adjusting the angle, which can effectively improve installation efficiency. For example, for rectangular symmetrically distributed holes, you only need to align the angle code with the installation part during construction to easily determine the drilling position, reducing measurement and calibration time. Although misaligned or irregularly arranged holes may have unique advantages in some special structural connections, they will increase the difficulty of installation and require more precise positioning and operation skills, and require higher experience from construction workers. Reasonable hole layout should follow the principle of "easy to locate and easy to operate" to make the installation process smoother.
The shape design of the hole is also closely related to the convenience of installation. The common circular hole is the most basic design, suitable for standard screws, with strong versatility, no special tools required for installation, and simple and easy to use. However, during the tightening of the screws in the circular hole, the angle code may be slightly displaced, affecting the installation accuracy. In contrast, the waist-shaped hole (long strip hole) provides more installation flexibility. Its long shape allows the screw to adjust its position within a certain range. If there is a slight size error or position deviation during installation, it can be fine-tuned through the waist-shaped hole without re-drilling or replacing the corner code, which greatly improves the fault tolerance and convenience of installation. In addition, the hole with countersunk design allows the screw head to sink into the hole, keeping the surface flat, which is both beautiful and does not affect the installation of other parts. It also reduces the risk of bumps caused by the protruding screw head and is widely used in scenes such as furniture assembly.
The dimensional accuracy of the hole directly affects the smoothness of installation. If the hole size does not match the screw, being too large or too small will cause installation problems. If the hole size is too small, the screw is difficult to screw in, and it may require force, causing the corner code to deform or even damage; if the hole size is too large, the screw will not be fixed tightly, the connection will be loose, and the structural stability will be affected. High-quality galvanized angles use high-precision processing technology to ensure that the hole size is perfectly matched with standard screws. The screws can be easily screwed in and tightened in place during installation without additional hole expansion or grinding operations, saving installation time and effort.
Whether the positioning mark of the hole is clear is also a detail factor that affects the convenience of installation. Some galvanized angles will set positioning marks such as scale lines and arrows near the hole to help construction workers quickly and accurately determine the drilling position. Especially in complex assembly structures, clear positioning marks can avoid incorrect installation caused by misreading the hole position and reduce the chance of rework. Angle codes without positioning marks require more time for measurement and calibration during installation, which reduces installation efficiency. Therefore, galvanized angles with clear positioning marks can significantly improve the convenience and accuracy of installation.
The requirements of the hole design for installation tools will also affect the convenience of installation. Some special hole designs may require special tools to complete the installation, such as hexagonal holes that require hexagonal wrenches, which to a certain extent increases the complexity of installation and tool costs. The galvanized angle with universal screw hole design can be installed with an ordinary screwdriver. It has low tool requirements and is easy to operate. It is more suitable for home DIY or small construction scenarios. When choosing a galvanized angle, considering the compatibility of the hole position with existing tools can effectively improve the convenience and economy of installation.
The anti-loosening design of the hole position is also related to the convenience of installation and long-term stability. Some galvanized angle holes will use anti-slip tooth patterns, thread reinforcement and other designs, which can effectively prevent loosening after the screws are tightened, reducing the subsequent maintenance costs. Although this design may require a slight increase in tightening force during installation, in the long run, it can avoid structural instability caused by loose screws, reduce the trouble of reinstallation or repair, and indirectly improve the overall installation convenience and user experience.
