Novalok is the market leader in New Zealand for coolroom and Freezer ventilated shelving, and has a complete range of specialist products for this market.

Novalok Duoguard Shelving is the market leader for chiller shelving systems in New Zealand. It has proved itself in the market over the last 25 years to be the best, the strongest, the most durable, the longest life, and the most user friendly system available.

This is largely due to the fact that Novalok was designed as a cool-room freezer shelving system from its inception, and not just an adaption of an industrial product.


The meaning of the name ‘Novalok Duoguard’:

Nova = A bright new star increasing in brightness (Oxford Dictionary).
Lok = Indicates the way it locks together with no nuts or bolts.
Duoguard = Is the ‘Dual’ protective coating, or guard against rust. This is firstly electro zinc plated and then epoxy powder coated. This dual coating works very well, as the zinc plated base coating is the best key for the second coating of powder coating, improving its adhesion immensely, then if the powder coating does get damaged, the Zinc plating is still there to offer excellent corrosion resistance. This system has proved so durable that we now give Novalok Duoguard a 15 year guarantee against corrosion.

Novalok Duoguard is the benchmark for commercial coolroom and freezer shelving systems in New Zealand.  It is the industry standard by which all other products are compared. There is more Novalok product in the coolrooms of New Zealand than any other single brand.

Novalok Duoguard is an very attractive, economically priced system, for use in any cool or freezer environments such as restaurants, universities, tertiary institutions, commercial kitchens, and drygoods storage areas.
