A steel greenhouse is the long-term option. It costs more at the start and gives back a structure that holds its shape, carries screens and irrigation, and can be upgraded rather than replaced.
Hot-dip galvanised steel is specified for humid, sometimes coastal conditions where corrosion, not load, is what ends a structure's life.
Height is the cheapest climate control there is. A taller house holds a larger air buffer, which softens the midday peak before any machinery runs.
Film, polycarbonate, and glass differ in light transmission, lifespan, and cost. The right pick depends on the crop and how long the facility must last.
A steel frame is worth specifying when you expect the operation to grow into more control than it starts with.
