Frequently Asked Questions

What forming speed is published for spiral silos?

The frequently asked questions material states a bending speed of up to 300 metres per hour. That is a forming speed, not a delivery time and not an installation time, and it should not be converted into a project schedule on its own.

What height and capacity figures are published?

The company profile states a height of up to 35.00 metres for spiral silos in general. The frequently asked questions material states a straight-section height of up to 31.5 metres, a height-to-diameter ratio of up to 5.75 and a single-silo maximum capacity of 6,500 tonnes. Those figures are general spiral silo figures from different source pages, and they must not be combined into a single guarantee that a given diameter, height and capacity all hold at the same time for a given product. Product-specific figures, where they exist, are given on the individual product pages.

Why do some figures differ between pages on this site?

Because the source documentation itself states some figures differently in different places. The grain silo design life is stated as 30 to 50 years in one section of its product page and as 25 years in another section. Spiral silo diameter is stated as 2.70 to 25.00 metres in the company profile and as 3 to 25 metres in the frequently asked questions material, and the grain silo page states both 2.7 to 25 metres and 3 to 25 metres. Cement silo capacity is stated in a truncated category summary beginning at 1000 and in a case index listing grades of 500, 1000, 3000, 5000 and up to 10000 tonnes. This site reports those differing statements separately and does not choose one of them. The applicable figure for a project is confirmed in writing during the inquiry process.

Are prices published on this site?

No. No price figure appears in the product documentation used for these pages, so no price is stated anywhere on this site. Cost factors are discussed in the cost guide, and prices are confirmed per project through the inquiry form.

How do I contact the supplier?

Through the inquiry form on the contact page. Contact details are not published on this site at present, pending confirmation of the correct contact information.

What certification does the company hold?

Certificates available upon request. The company profile describes a second-class professional contracting qualification for steel structures, but no certificate number or issuing document is published here. Design standard statements on product pages, such as D-4097 or ASTM D-3299, are design standard statements for those products, not company certifications.
