The traditional way of manufacturing HeliGrids is very expensive, precise and difficult. They are manufactured from one large plate, that is often on a twelve month plus lead time. The machining process requires large, capital-intensive machines that have to tie up thousands of individual features without an error. The material cannot be repaired if an error is made, making their manufacture very high risk.
Contemplating this problem through our R&D department, we believed that there must be a better way. So the concept of the Modular HelliGrid (MHG) was born. The concept is simple: you make each hole individually. Minimal material lead time, lower material costs, lower machine capital costs, lower risk. Components can be held in stock, delivering a MHG in weeks not years. Shipping is easier in crates, and if you damage one in service it is repairable.
