Bulk Grain Storage Solutions

Spantech horizontal bulk grain storage buildings are a very cost effective long term storage solution. They present excellent value for money for grain and other bulk agricultural commodities.

Types of Grain Stores

Ground to Ground Grain Stores

Spantech’s most cost effective agriculture buildings are the ground-to-ground arched building design. Spantech Woomera 300 profiles are connected to concrete footings to provide a free-spanning arched building similar to the WWII Nissen Hut.

 Importantly, Spantech’s modern interpretation of this design does not require any internal structure. Spantech’s wide-span arch technology creates a smooth internal finish. 

The uncluttered wide open space is ideal for the storage of grain and other bulk produce.  The shape of the building also allows grain to be stacked directly against the curved walls of the building.

Wide-Span Bulk Grain Storage

Wide span bulk grain storage buildings are constructed at large inland grain depots and shipping ports.

Glencore New Zealand currently operates four Spantech bulk grain storage facilities at ports on both the North and South Islands of New Zealand. Spantech bulk stores are constructed with the Spantech Pinkenba 370 profile.

These wide-span metal profiles are connected to load bearing reinforced concrete walls between 4 metres and 8 metres high. The walls are designed to support direct product loads.

Glencore’s Mount Maunganui Bulk Grain Storage facility designed by Spantech features the Pinkenba 370 profile roofing system for an extra wide free-span curved roof.

Fully Sealed Buildings

The Spantech Pinkenba 370 and Woomera 300 profiles provide a clean internal finish, free of internal supports.  This smooth internal finish can be sealed to allow fumigation of stored product.


Spantech offers excellent natural lighting with low profile skylights. Artificial lighting features commercial quality low heat LED lighting.  Fittings can be surface mounted directly to the Spantech curved roof to minimise dust accumulation and eliminate vermin roosts. Where extreme fire risk exists, light fittings can be installed outside the building with light directed through insulated glass ports.  The fittings can be safely accessed via the roof access system.


Passive and mechanical ventilation systems are available.  Where buildings are sealed for fumigation, all vents can be mechanically sealed.
