Quality & Testing Laboratory

Tested In-House, Before It Ships

Every National Plasto product is engineered with high-impact polymer formulation, UV weather stabilizers and reinforced stress-point ribs. Our in-house quality checks run from resin feed to final dispatch, under a quality management system certified to ISO 9001:2015 at all four plants.

Load-Bearing Strength

Chairs are tested to withstand up to 200 kg of static and dynamic loads, so seating holds up to everyday home, commercial and institutional use.

200 kg static & dynamic load tested

Material Quality

Polymer batches are checked before moulding, and formulations include UV weather stabilizers for products used indoors and outdoors.

High-impact polymer & UV stabilized

Moulding & Dimensional Checks
