Does Antai hold up in Thailand's climate?

Antai is rated for wind loads up to 60 m/s and snow loads up to 5400 Pa. It is certified to UL 2703, IEC 61730, and ASTM B117 (1000-hour salt spray) — well suited to Thailand's climate.

What materials does Antai use?

Rails and L-Feet are anodized aluminium 6005-T6. Bolts and hooks are Stainless Steel 304 — salt and rust resistant, with a service life of 25+ years.

Which model for metal sheet vs tile roofs?

Metal sheet / Klip-Lok: use L-Feet H85 or H165, or L-Feet for Klip-Lok. Tile roofs: use Tile Hook, which slides under the tiles and fastens into the roof frame.

How Mounting Components Are Calculated (Formulas)

Rail: 2 rails per row of panels; total length = row width
End Clamp: 4 per row (outer edge on both sides × 2 rails)
Mid Clamp: 2 × (panels per row − 1) per row (between panels)
Rail Splice: used when joining multiple rails in a single row

L-Feet / Tile Hook: every 1.2 metres along the rail
Grounding Clip: equal to total clamp count (End + Mid)
Grounding Lug: 2 per row (for connecting the ground wire to earth)

Figures are estimates. Allow 5-10% spare parts and consult a QES Energy engineer for accurate, site-specific calculations (wind load / roof pitch).
