Surface Treatment Technology for Stainless Steel Guardrails

High-end materials

Material: Made of GB standard Q-235A steel.

2. Welding Technology: Utilizing CO2 gas shielded welding (uniform welding points, strong airtightness, and excellent durability). Welding rods.

Handcrafted Iron Artistry: Hand-forged iron craftsmanship.

3. Surface Treatment:

Hot-Dip Galvanizing Processing

Electrostatic Powder Coating: No need for thinners, environmentally friendly with no harm to humans during application; excellent coating appearance quality, strong adhesion and mechanical strength; short curing time for spraying process; superior corrosion and abrasion resistance; no need for primer; easy to apply with low technical requirements for workers; lower cost than painting; some construction sites have explicitly required the use of electrostatic powder coating; no dripping occurs during the electrostatic powder spraying process, which is a common issue in painting techniques.

Mid-range material

Material: Non-standard Q-220B grade steel used.

2. Welding Process: Utilizing manual welding techniques.

Iron Craftsmanship: Primarily utilizes cast iron or standard profiles for bending into floral designs.

3. Surface Treatment:

Cold galvanized or uncoated
