Purchasing guide for industrial-grade handles

1. Material selection: The basis for determining the service life of the handle

Stainless steel is the first choice for industrial handles, among which 304 stainless steel has become the most common choice due to its excellent corrosion resistance and moderate price. For harsh environments such as coastal areas or chemical sites, 316 stainless steel is recommended. The addition of molybdenum can significantly improve the chloride corrosion resistance. In special scenarios, such as petrochemical fields with strict explosion-proof requirements, copper alloy or stainless steel composite materials may need to be considered.

2. Load-bearing capacity: the core indicator to ensure safe use

The load-bearing capacity of industrial handles is directly related to the safety of use. Light handles usually bear a weight of less than 50kg and are suitable for ordinary cabinets; medium handles bear a weight of 50-100kg and are suitable for most industrial equipment; heavy handles can bear a weight of more than 100kg and are used for large machinery or heavy door bodies. When purchasing, the dynamic load in actual use should be considered, and it is recommended to choose a product with a load-bearing capacity 30% higher than the actual demand to ensure a safety margin.

3. Surface treatment process: affects durability and maintenance costs

Common surface treatment processes include:

● Wire drawing treatment: provides good wear resistance and moderate anti-fingerprint effect

● Mirror polishing: easy to clean but easy to leave scratches

● Sand blasting: Provides optimal scratch resistance and slip resistance

In industries with high hygiene requirements such as food and medicine, it is recommended to choose mirror surface or wire drawing treatment; in heavy industry or outdoor environments, sandblasting treatment is more suitable.

4. Installation method: affects ease of use and security

The main installation methods include:

● Screw fixation: the most common, simple to install and easy to maintain

● Embedded: Beautiful and safe, but complex to install

● Welded type: the strongest, but not detachable

Door material, frequency of use and maintenance requirements should be considered when selecting. Frequently opened doors are recommended to be screwed for easy replacement, and heavy equipment may require welded installation.

5. Special environmental adaptability: ensure long-term reliable use

For special work environments, consider:

● High temperature environment: High temperature resistant materials and special coatings are required

● Humid environment: Higher grade stainless steel and anti-rust treatment are required

● Clean environment: Choose a style that is easy to clean and leaves no dead spots
