For grain, fertiliser, and cotton storage, Ridge Steel offers economical arch‑formed steel buildings that maximise internal volume with minimal material usage. Our curved, self‑supporting panels are fabricated from high‑yield galvanised steel, providing excellent ventilation and natural light diffusion through optional translucent strips. With clear spans up to 40m and no internal columns, these structures allow unobstructed loading/unloading using front‑end loaders. We provide complete design‑to‑erection service, tailoring roof pitches and end‑wall layouts to suit local conveying equipment – a cost‑effective solution proven across hundreds of agricultural sites in Southeast Asia.
