NAVANA ENGINEERING LTD.
Navana Engineering Ltd.

An ISO 9001:2008 Certified Company

Testing & Inspection Facility

Navana Engineering Ltd has a well-equipped Quality control laboratory with all modern for Chemical, Physical and Mechanical Testing properties of basic raw material, Pipe, Socket and Galvanizing.

Quality control is the watchword and we believe that quality assurance begins at the raw materials stage itself. There is a reason why we source raw materials for plastic pipes from none other than prime producers from home and abroad. Materials are subjected to visual inspection and dimensional checks. Chemical composition and mechanical property are also tested to ascertain its conformity to relevant standards. The materials get approved by National and International Inspecting Authorities like ISO, WRAS, DIN, BSTI, BUET and RUET and many more assuring our customers quality and 100 per cent satisfaction in every aspect.

Research and Innovations

Our R&D team continuously strives to reduce various costs and increase operational efficiencies so as to enable us to deliver high and products with quality and cost-effectiveness.
