Product Overview
H-section steel mastfrom hot-rolledH-section steel masts body, flange base, end connection plates and related parts, the number in the model is the mast body section height (mm), the fraction the mast height (m). the mast base connects to the foundation via flange and anchor bolts, leveled by adjusting nuts then fastened; fully hot-dip galvanized, meeting long-term outdoor service requirements.Common specifications below:
| Model | Section height(mm) | Mast height(m) |
|---|---|---|
| GH240X/7.5 | 240 | 7.5 (common range7.5~11) |
| GH260X/7.5 | 260 | 7.5 (common range7.5~11) |
| GH270X/7.5 | 270 | 7.5 (common range7.5~11) |
| GH280X/7.5 | 280 | 7.5 (common range7.5~11) |
| GH300X/7.5 | 300 | 7.5 (common range7.5~11) |
Note: ：mast height is chosen by track-level difference and foundation surface, GH270X height class per the certified technical documents.
