Composition of Vitreous Enamel
Compliance
VETOP® aims to be the industry leader in vitreous enamel production durability, reliability and quality. To accomplish this goal, we have set up a dedicated team of engineering professionals and managers to ensure that our products always exceed the strictest and highest International Standards*.
All VETOP® products are subject to a series of rigorous quality assurance procedures to maintain high-levels consistency. The following three key areas summarize our testing and internal quality control procedures:
Certificate of Hong Kong Q-Mark Product Scheme
Hong Kong Q-Mark Product Scheme Licence No.: T182-SZ
Pre-treatment
Pre-treatment system is checked and tested once a week or after each order batch, whichever is shorter, to ensure every vitreous enamel product is completely contamination free before coating.
Enameling
Every vitreous enamel panel is tested according to the comprehensive set of policies and inspection procedures to ensure coating thickness, surface finishing and colour matching.
Lab Test
Three finished samples are selected and tested from each production order in compliance with BS 1344, to ensure the quality maintains consistency and its performance in the project environment.
