Basalt and Granite Quality Control Training in Qui Nhon

In December 2016, we held a training course for the QC team at Qui Nhon quarry and factory for Vietnam Basalt and Granite products.

The course included 3 sections with the main purpose being to give an update in the quality standard of Basalt and Granite products as well as to learn from experience.

In the first section, we focused on the quality standard of Basalt products. There were some highlight points on each kind of Basalt Product:

• Basalt cobble: even surface, no dent in edges, right dimension especially in thickness of product.
• Basalt Palisade/kerb sawn then hand-splited: even surface, square edges, avoid white marks.
• Basalt Palisade and Step/stair flamed (thermal): select suitable material from the quarry, the surface after flamed must be smooth, with no white marks or bee holes, and avoid dent in the edges
• Basalt slab/tile flamed and brushed (thickness 2-3cm): ensure tolerance +/-1mm in thickness, even and smooth surface, square edges without dent.

Following, we discussed quality of Granite products in the quarry and factory:

• Yellow (Gold) Granite: classify into 5 levels based on shades (from light to dark) and use each level to different customers follow their requirements.
• Light grey (White) Granite: select material without black/brown marks with a diameter bigger than 2cm.

In the end, we reviewed significant cases of product quality that had occurred in the year to find solutions and learn experience from each case. We emphasized the importance of learning new knowledge from experience and from each requirement of customers. The team started to bring what they learned into practice promptly.

Bringing customers the finest quality products is our first priority. Therefore, we have improved constantly our skills and knowledge, from quarrying to manufacturing and to quality controlling. We are proud to be the reliable Vietnam natural stone supplier of many customers for over 15 years and we keep that as our motivation to contribute more to our valued customers all over the world.
