The Galv Ground Socket Structural Pipe Fitting is a key component for upright installation in construction and industrial projects. It ensures secure embedding in different ground conditions, providing excellent stability and resistance against loosening. With its durable structure, high-strength materials, and corrosion-resistant finishes, this fitting guarantees long-lasting performance. HULK Metal offers customized specifications, making it suitable for a wide range of environments and global application requirements.
The Galv Ground Socket Structural Pipe Fitting is designed to be embedded into the ground to provide a reliable socket for uprights. It is especially useful in outdoor installations, fencing systems, and structural frameworks. The upright can be easily fixed or removed by tightening or loosening the hexagon bolt. On concrete floors, holes must be drilled before inserting the socket. This fitting enhances stability, prevents movement, and simplifies replacement of uprights when necessary. It is widely applied in temporary structures, construction sites, and permanent installations requiring firm and adjustable ground connections.
The socket body features two protrusions on the outside to increase friction with the ground and prevent it from being pulled out when the upright is removed. An inclined hexagon bolt is inserted into the socket to lock the upright firmly in place. This design makes the fitting more secure, easy to operate, and convenient for installation or dismantling.
Multiple material options ensure strength, durability, and adaptability to different projects, from heavy-duty construction to lightweight and corrosion-resistant applications.
Available in malleable iron and ductile iron, cast iron fittings provide excellent strength and wear resistance. Malleable iron is ideal for general-purpose structural projects, while ductile iron offers higher toughness and impact resistance. Both materials are cost-effective and meet strict international standards, making them the preferred choice for bulk orders in global construction projects.
Stainless steel ground sockets provide superior corrosion resistance, especially in coastal, marine, or humid environments. They are designed for long service life with minimal maintenance. Stainless steel fittings also deliver strong mechanical properties, ensuring structural integrity under various conditions. They are recommended for high-end projects where aesthetics, durability, and performance are equally important.
Aluminum fittings are lightweight yet strong, making them suitable for projects that require easy handling and installation. Their natural corrosion resistance ensures performance in outdoor conditions without significant surface degradation. Aluminum sockets are ideal for temporary or portable structures and projects where reducing overall weight is important, such as exhibition frameworks, lightweight railings, and mobile equipment supports.
Different surface treatments provide enhanced protection, extended durability, and make the fittings adaptable to diverse environmental and project conditions.
Hot-dip galvanizing provides a thick and uniform zinc coating, ensuring excellent corrosion resistance and long service life. This method is suitable for outdoor applications, construction projects, and areas with exposure to moisture. The protective layer prevents rusting and withstands harsh environments, reducing maintenance costs. With strong adhesion and durability, hot-dip galvanized sockets are widely used in fencing, guardrails, scaffolding, and permanent outdoor structures.
Double-coating galvanizing combines hot-dip galvanizing and electro-galvanizing to create an even more durable and protective surface. The first layer offers robust corrosion resistance, while the second layer enhances smoothness and aesthetic appeal. This method is suitable for environments with high humidity, industrial exposure, or where a more refined appearance is required. It ensures long-term performance, better wear resistance, and added protection against scratches or surface damage.
l Confirm whether the Galv Ground Socket size can meet your system requirements and match the tube dimensions.
l Ensure the selected surface treatment can resist the environmental conditions where the product will be used.
l Check if the socket complies with local installation and safety standards.
