An Introduction to Coresteel’s Structural Systems

Coresteel has built over 2000 commercial and industrial buildings for businesses across New Zealand. We use two exclusive structural systems to create tailored building solutions for our clients: the Bracketless Portal System and the DonoBeam. These unique systems enable businesses to make the most of their internal space and facilitate greater business growth.

From retail spaces, showrooms, and factories, to storage facilities, warehouses, and workshops, our versatile systems have been applied in a range of successful projects. Learn more about our steel structural systems below.

The DonoBeam System: Wider Spans for More Internal Space

As the most innovative construction system in our range, the DonoBeam is the ideal choice for investing in your industrial or commercial premises. This system offers clear spans of up to 75m, allowing for greater internal space than ever before. Our tallest building to date reaches a height of 18M – and we can go even higher.


What’s the Process?

The beam is created at Coresteel’s high-tech NZ manufacturing plant by folding two halves of steel plate and welding them together to form a long box shape. When the steel frame is complete, the project is packaged with all the necessary fastenings and delivered to the site in a structural kit set. The fully bolted structure has no obtrusive knee or apex braces, which allows for more usable space within the building. Every square meter of your new commercial space can be utilised to maximise your business growth.


Economical & Environmental Benefits

The DonoBeam system offers significant cost benefits for our industrial and commercial clients. Since each steel structure is pre-fabricated before it is delivered to your site, the labour process is quick and simple. This means that less staff are required on site, and labour costs are vastly reduced.

Due to its tapered length, the Box system also requires less steel than traditional industry standards – resulting in reduced steel wastage. Not only does this reduce costs, but it also has a positive impact on the environment. By only producing the amount of steel required for the project, we significantly cut down on our carbon emissions. Less paint is also needed due to the reduced surface area, which provides further cost savings. Additionally, the beams are bird and vermin resistant, which means your building will remain in good physical condition for longer periods of time. This is particularly helpful for food storage business facilities that require extra protection from vermin.


Tailored Building Solutions for Every Project

The innovative nature of the DonoBeam allows Coresteel to create sleek and stylish building designs that are unique to every project. Every building is custom-made to meet your clients’ specific business needs – so no project is the same. Using the DonoBeam, we have completed a vast number of large-scale construction projects, ranging from commercial warehouses and waste facilities to modern reception areas and attractive showrooms. Architectural features such as branded store fronts can be easily applied to make your business stand out on the market.


The Bracketless Portal System: Designed for Efficiency & Appeal

In addition to the DonoBeam, our Bracketless Portal System has been used extensively in steel building construction. Introduced in 2005, this patented, cold-rolled system has been designed for efficiency, flexibility, simplicity and appeal. It offers many of the same benefits as the Tapered Box Beam, but with a span range of 9m to 30m. Like the DonoBeam, the goal of this system is to allow businesses to make the most of their internal space, with no interfering centre poles or braces.

During the construction process, steel columns and rafters are bolted together, rather than being joined with an obtrusive knee bracket. This allows for a stronger connection between the sections, as well as faster construction times and reduced labour costs. Over the years, we have produced a wide range of projects using this system, including retail shops, storage facilities, and commercial company headquarters.
