About us

Built on a single mission

G.N.K. Sons (Pvt.) Ltd. was founded in 1987 by Afzaal Nabi Khawaja as a small facility making safety workwear. Within a few years it was supplying major companies, producing hundreds of coveralls a day with more than 300 people, and shipping across the Middle East and Australia.

Since 2012 a wider product range has taken GNK into Europe. Today a new generation runs the business with the same work ethic it started with, and with modern materials that make workers safer than ever.

“Protecting human beings while they work.”
