The Cradle Clamp Structural Pipe Fitting combines durability, safety, and ease of installation. Its open clamp design allows pipes to be positioned quickly, while hex bolts secure them firmly to uprights. Manufactured from malleable or ductile iron, with customizable surface finishes, it adapts to diverse environments. HULK Metal ensures precise dimensions, strong load-bearing capacity, and reliable corrosion resistance. This fitting is ideal for industrial, commercial, and architectural railing systems.
The Cradle Clamp Structural Pipe Fitting is specifically designed to hold pipe rails securely on uprights. Its structure features an open clamp, allowing pipes to be placed quickly and adjusted easily, saving installation time. The socket includes an inner hex bolt to fix the fitting onto the upright, while another hex bolt secures the pipe firmly in place.
This fitting is widely used in safety railings, walkways, scaffolding systems, and industrial platforms where strong, reliable support is essential. Its robust design ensures minimal movement of pipes, maintaining structural stability under heavy loads or frequent use.
HULK Metal manufactures these fittings from high-quality malleable iron or ductile iron, ensuring excellent strength and durability. The fittings can be treated with galvanizing, powder coating, or other customized surface finishes to resist corrosion and withstand harsh environmental conditions.
With strict dimensional standards and quality control, each Cradle Clamp fits accurately and reliably, reducing on-site adjustments and installation errors. It is a cost-effective and long-lasting solution for bulk procurement, meeting the needs of industrial, commercial, and architectural projects worldwide.
High-strength malleable iron, ductile iron, stainless steel, or aluminum, providing durability, corrosion resistance, and compatibility with various projects.
Cast iron offers excellent compressive strength and durability, making it suitable for heavy-duty applications. Its rigid structure ensures minimal deformation under load, providing stable pipe support for industrial and commercial railings. With proper surface treatment, cast iron cradle clamps resist corrosion, extend service life, and maintain a professional appearance in demanding environments.
Stainless steel cradle clamps provide superior corrosion resistance, ideal for outdoor or humid environments. Their smooth finish prevents rust and requires minimal maintenance, ensuring long-lasting performance. These fittings are strong yet lightweight, combining durability with aesthetic appeal. Suitable for marine, architectural, and industrial applications, stainless steel clamps maintain structural integrity while offering a sleek, modern look.
Aluminum cradle clamps are lightweight and corrosion-resistant, making them easy to handle and install. Ideal for indoor and outdoor applications, they resist rust and maintain strength over time. Although lighter than cast iron or stainless steel, aluminum fittings provide reliable support for medium-load systems, and their anodized or powder-coated finishes enhance both durability and visual appeal.
Galvanizing, powder coating, and customized finishes provide long-lasting protection, corrosion resistance, and suitability for different environmental conditions.
Hot-dip galvanizing applies a thick zinc coating to the cradle clamp, providing excellent corrosion resistance in industrial and outdoor environments. This process protects against moisture, chemicals, and wear, extending the service life of the fitting. Ideal for coastal areas, factories, or outdoor walkways, hot-dip galvanizing ensures long-term durability and minimizes maintenance costs. The coating is uniform, strong, and capable of withstanding rough handling and heavy loads.
Double-coating galvanizing adds an electroplated zinc layer on top of the hot-dip galvanized surface, offering superior corrosion protection. This dual-layer treatment enhances durability, reduces surface imperfections, and improves wear resistance. It is especially suitable for harsh or coastal environments, industrial structures, and long-term outdoor installations. The combination of hot-dip and electroplated coatings ensures both structural strength and aesthetic finish, providing extended service life for bulk procurement projects.
Powder coating provides a protective and decorative finish for cradle clamps. Applied electrostatically and cured under heat, it creates a uniform, durable layer that resists corrosion, UV exposure, and scratches. Available in customizable colors, powder-coated fittings suit both industrial and architectural applications where aesthetics and longevity matter. This finish allows for flexible design choices while maintaining strong structural performance, making it ideal for large-scale projects requiring consistent quality and appearance.
