We are a machining factory with sheet-metal roofs, and after a day in the sun the workshop temperature hits around 40°C — hard on the workers and heavy on air-conditioning power. After pulling shade net over the roofs, the temperature underneath dropped several degrees, the workshop is far cooler, AC load came down, and we save noticeably on electricity. Raw materials and finished goods in the open yard are also protected from sun aging. The net comes in wide widths, so covering a whole roof leaves fewer seams; fixed with steel wire and battens, it holds steady in strong winds and shows no brittleness after years of use. For factories, shade netting is the cheapest cooling and cost-saving measure available — we have installed it on several workshops.
