Sand Blasted 304 Stainless Steel Laser Cutting Bending Cover with 50-80 Grit Uniform Finish

This sandblasted 304 stainless steel cover combines laser-cut precision with press-brake forming for consistent 1.5-3mm gauge tolerances. The 50-80 grit finish delivers a non-directional matte surface, enhancing corrosion resistance while minimising fingerprint retention. The textured surface improves grip in industrial settings and allows for touch-up repairs without visible blending.

Glass Bead Shot Blasting

Glass bead shot blasting process ‌ is a process that uses glass beads as shot blasting material for surface treatment. Specifically, shot blasting process is to mechanically throw glass microbeads to the surface of the workpiece at high speed, remove dirt, oxide, welding slag and other impurities on the surface of the workpiece through high-speed impact, and improve the quality and roughness of the surface, enhance the wear resistance and beauty of the surface .






Product Advantages of Sand Blasted 304 Stainless Steel Laser Cutting Cover




  • Material Integrity: AISI 304 stainless steel (18% Cr, 8% Ni) ensures superior corrosion resistance, complying with BS EN 10088-2 for austenitic grades, ideal for harsh environments (chemical, marine, or high-humidity).

  • Precision Fabrication: CNC laser cutting achieves ±0.1mm dimensional accuracy, paired with press-brake forming for consistent 1.5-3mm gauge retention, eliminating weld-induced stress points.

  • Functional Surface Finish: 50-80 grit alumina blast creates a uniform, non-directional matte texture (Ra 3.2-6.3µm), reducing light reflection, masking minor abrasions, and enhancing grip in oily/wet conditions.

  • Aesthetic Versatility: Neutral matte finish seamlessly integrates with architectural cladding or industrial machinery, avoiding glare while resisting fingerprint marks.

  • Repairability:  Localised surface damage can be re-blasted without visible blending, unlike polished or brushed finishes, reducing lifecycle costs.

  • Custom Compatibility: Pre-treated surface accepts powder coating or PVD overlays without additional profiling, enabling brand-specific colour matching.




Product Use of Sand Blasted 304 Stainless Steel Laser Cutting Cover:


  • Architectural Cladding: Exterior façades, column covers, and signage panels requiring corrosion resistance, low visual glare, and seamless integration with modern design aesthetics.

  • Food & Pharma Processing:  Hygienic equipment housings, conveyor guards, and inspection hatches compliant with NSF/EN 1672-2 for washdown environments and microbial control.

  • Marine Infrastructure: Offshore platform components, dock-side control cabinets, and shipboard fixtures exposed to saltwater spray and UV degradation.

  • Medical Facilities: Sterile instrument housings, MRI room fixtures, and lab ventilation ducts demanding non-magnetic properties and chemical sterilant compatibility.

  • Public Utilities:  Subway station ticket kiosks, wastewater treatment plant control boxes, and street furniture engineered for vandal resistance and minimal maintenance.

  • Laboratory Equipment:  Fume extraction hoods, cleanroom access ports, and cryogenic storage housings benefiting from thermal stability and acid/fume corrosion resistance.

  • Consumer Durables:  Premium kitchen appliance trim and outdoor grill components balancing aesthetic appeal with fingerprint/scratch resistance.

FAQ:


1Q: Why choose laser cutting process for this item?

1A: Due to the small quantity demand. If customer has large quantities, we could use stamping process to make it.


2Q: Is the glass bead shot blasting the same with common sand blasting?

2A: No, they are different. The media is different.


3Q: Can you offer free samples?

3A: Yes, we could provide 3-5pcs free samples if customer requires. And customer needs to pay for the half tooling/fixture cost firstly.


4Q: Does laser cutting part need a mold or tooling?

4A: No, it does not need a tooling or mold. But it may need a fixture.


5Q: Can you arrange them to sea ship to customer?

5A: Yes, we can. No matter sea shipping, air shipping or express shipping, all are ok to proceed.
