Features
What makes the ST-100-SH work, part by part.

Coated Steel Frame
An all-steel frame with a zinc-aluminum-magnesium alloy coating that resists UV, heat, windblown sand and corrosion. 100 × 100 mm posts, rated at 70 kg/m².

Wide 180 mm Louvers
Large 180.3 × 34.5 mm blades span the whole roof. Open them by hand for air and light, close them for shade.

Integrated Drainage
A 54×32 mm gutter is built into the frame, so rain runs off the closed louvers into the gutters instead of onto the seating area.
