Product Overview
The CL-HDG-HD is Dengtai”s heavy-duty caged ladder — engineered for industrial environments where standard 150 kg load ratings are insufficient. Q345B high-strength structural steel, thicker coating (100+ microns HDG), and reinforced bracket connections support 250 kg concentrated load per rung.
What Makes This Model Different
- Q345B high-strength steel: Higher yield strength than standard Q235B. Allows higher load ratings without increasing section dimensions — the ladder weight and footprint are similar to standard models.
- 250 kg load rating: For facilities where maintenance personnel carry heavy tools, where multiple workers may be on the ladder simultaneously, or where equipment may be hoisted via the ladder structure.
- 100+ micron HDG coating: Thicker than the standard 80 microns. Provides additional corrosion protection for aggressive industrial atmospheres — metal finishing shops, foundries, chemical storage areas.
- Reinforced brackets: Heavier gauge steel, additional anchor points per bracket. Designed for the higher static and dynamic loads of heavy industrial use.
When to Choose This Model
Choose the CL-HDG-HD when: your facility”s safety assessment requires load ratings above the standard 150 kg; the ladder serves equipment platforms where maintenance crews carry heavy tooling; forklift proximity creates potential impact risk (reinforced construction provides additional damage resistance); or your corporate safety standard exceeds the regulatory minimum for load rating.
