When sourcing steel lab tables, the grade of steel and the worktop material are paramount. You should prioritize Cold-Rolled Steel (CRS) with a thickness of at least 1.0mm to 1.2mm for the frame to ensure structural stability. For the worktop, depending on the usage, choose between Phenolic Resin (best for general chemistry), Epoxy Resin (superior heat and chemical resistance), or 304/316 Stainless Steel (ideal for sterile environments and heavy moisture). Ensure the steel surfaces are treated with an Epoxy Powder Coating to prevent corrosion from acid and alkali exposure.
