What's the B grade quartz stone?

In the quartz stone industry, a Grade B slab (also called Commercial Grade or Second Choice) refers to a quartz slab that meets basic performance standards but shows minor visual imperfections compared with a Grade A slab.

Although Grade B slabs are fully usable and structurally reliable, they may not meet the highest aesthetic standards required for premium projects. 

Advantage of Grade B Engineered Stone Slabs

Same Structure, Slightly Lower Appearance Quality

Grade B slabs maintain normal density, hardness, and durability, but may include:

• Slight color variation or inconsistent tones

• Small pinholes or particles on the surface

• Minor texture differences compared with the original design

• Localized gloss inconsistency

• Light forming marks or subtle streaks

These imperfections do not affect basic performance or daily use.

Why Do Grade B Slabs Occur?

Grade B artificial stone slabs are usually generated during production due to:

• Uneven particle distribution

• Slight color dispersion differences

• Temperature fluctuation during curing

• Minor vibration/pressing inconsistencies

• Natural variation in raw materials

These factors result only in aesthetic differences, not structural issues.

Summary

Care & Maintenance

Quartz offers the beauty of natural stone with added durability and low maintenance—just a few simple steps keep it looking flawless.
- Clean daily with a soft cloth and mild dish soap or a non-abrasive surface cleaner—no need for heavy-duty chemicals or sealers.
- Wipe spills promptly, especially from coffee, tea, wine, or tomato-based products to avoid discoloration over time.
- Use cutting boards and trivets—quartz is tough, but direct heat and sharp blades can still cause damage.
- Avoid abrasive pads and harsh chemicals, including bleach, oven cleaner, or anything acidic, which can dull or damage the resin.
- Dry thoroughly after cleaning to maintain the surface’s glossy finish and avoid watermarks.
