Rivet Nuts for Prefabricated Houses

In prefabricated houses, rivet nuts are key components in the assembly and fastening process. The DunChuan handheld press rivet nut, with its advantages of cold pressing and strong adaptability, has become an efficient solution to address the pain points of traditional processes.

Drawbacks of Traditional Fastening Processes

In the assembly of traditional prefabricated houses, welded nuts and ordinary rivet nuts have significant drawbacks:

• Welded Nuts: High-temperature welding can damage the zinc coating or anti-corrosion coating on the surface of the sheet metal, leading to material embrittlement and rust, thereby shortening the service life of the sheet metal. Additionally, the welding process may cause thermal deformation, affecting assembly accuracy. The construction process is cumbersome, inefficient, and poses safety risks.
• Ordinary Rivet Nuts: They require pre-drilling, adding steps and compromising the structural integrity of the sheet metal, which can lead to loosening at the fastening points. Their poor adaptability makes them incompatible with sheet metals of different thicknesses or materials, limiting their application scenarios.

Core Advantages of DunChuan Handheld Press Rivet Nuts

DunChuan handheld press rivet nuts redefine the assembly and fastening process of integrated houses through cold pressing technology:

• Cold Pressing: No high-temperature welding is required, preventing damage to the surface coating of the sheet metal, maintaining anti-corrosion performance, and extending service life. The cold pressing process is free of thermal deformation, ensuring assembly accuracy.
• Precision and Efficiency: Paired with a dedicated handheld press riveting device, it is easy to operate and can quickly complete fastening tasks, significantly improving construction efficiency.
• Strong Adaptability: Compatible with sheet metals of different thicknesses (e.g., 0.8-3.0mm) and materials (e.g., stainless steel, carbon steel), meeting diverse needs.
• Solving Traditional Pain Points: By eliminating issues such as high-temperature damage and structural damage through cold pressing technology, it enhances the consistency and durability of fastening points, becoming a core tool for cost reduction and efficiency improvement.

Material and Specification Selection for Rivet Nuts

There are various types of rivet nuts on the market, and selection should be based on the application scenario:

• Materials: 201 stainless steel is suitable for general environments; 304 stainless steel offers stronger corrosion resistance and is ideal for humid or corrosive environments; galvanized carbon steel is cost-effective but has weaker corrosion resistance than stainless steel.
• Specifications: Common specifications include M3, M4, M5, M6, M8, M10, etc., and should be selected based on the thickness of the sheet metal and load requirements.
• Surface Treatments: Treatments such as galvanizing, passivation, polishing, and chrome plating can enhance corrosion resistance or aesthetics, and should be chosen based on environmental needs.

Price Differences and Selection Recommendations

The prices of rivet nuts from different manufacturers are influenced by factors such as material, specifications, and process. It is recommended to prioritize products that comply with national standards (e.g., GB/T 17880) and consider both cost and performance needs to select a cost-effective solution.
