What’s the difference between Spelsberg enclosures and cheaper alternatives from China?

Short answer

Spelsberg enclosures are manufactured to a higher specification than many budget imports, using tested materials and construction methods verified to relevant EU and industrial standards. All Spelsberg non-metallic enclosures are halogen-free and manufactured in accordance with RoHS and WEEE requirements, a standard not consistently met by lower-cost alternatives.

Electrical enclosures are tasked with the job of protecting your electrical connections and components from the outside elements. Depending on the application and environment this can include water and dust ingress, temperature fluctuations, collisions and impacts, corrosive atmospheres, explosive environments, exposure to chemicals and even deliberate sabotage.

The fundamental difference between Spelsberg enclosures and the cheaper alternatives that are available is that Spelsberg products have been manufactured using the latest techniques and from the best quality materials. They have also been tested extensively, to all relevant EU and industrial standards, to ensure that they offer suitable levels of protection.

For example, all Spelsberg non-metallic enclosures are halogen free and manufactured in accordance with RoHS regulations and the WEEE directive. It has been shown that some ‘budget’ enclosures entering the market to not meet the same standards.

Spelsberg offers solutions ranging from entry level, Polystyrene junction boxes through to fully customised, GRP enclosures. At each price point we are able to compare are our products to alternatives on the market and offer either distinct performance improvements or extremely competitive costing.
