Features Of This PPE Product
Delta Health and Safety is a strong team that has been working together for many years. Established in 1994, Delta is as old as our new South Africa. The core team has a combined history in PPE of over 100 years. Many of the people we deal with say that we have a stable, warm, family-style company culture.
We sell quality fit-for-purpose PPE to end-users and resellers. We don’t position our products based on pricing, but on being the right protection for the work application. Our team is more technically inclined, often digging a little deeper to better understand your needs, and so recommend the best solution for you. This means that we need to be thorough, ask lots of questions, and be curious by nature.
