FAQ

Frame Scaffolding — Frequently Asked Questions

What is the difference between A-frame and H-frame scaffolding?
An A-frame (main frame) has a walk-through opening shaped like an 'A', allowing workers to pass through easily. An H-frame has horizontal cross bars forming an 'H' shape for extra rigidity. Both are welded tubular frame systems using Q235/Q345 steel tubes (OD 42.7mm). Main frames typically come in 914mm and 1219mm widths with heights of 1530mm, 1700mm, and 1930mm.
What surface finishes are available for frame scaffolding?
Frame scaffolding is available in four surface finishes: pre-galvanized (zinc-coated tube before welding), painted (red/blue/yellow primer paint, most economical), powder coated (durable colored finish), and hot-dip galvanized (thick zinc coating after welding for maximum corrosion resistance, ideal for coastal and humid environments).
What sizes are available for main frame scaffolding?
Main frame scaffolding is available in three widths: 762mm (2.5ft), 914mm (3ft), and 1219mm (4ft). Heights: 1530mm, 1700mm, and 1930mm. Tube diameter is OD 42.7mm with wall thickness ranging from 1.8mm to 2.5mm depending on load requirements. Custom sizes are available upon request.
What components are included in a frame scaffolding system?
A complete frame scaffolding system includes: A-frames (main frames) or H-frames, cross braces (X-braces), joint pins (coupling pins), C-locks or arm locks for securing braces, base plates or screw jacks, metal decks/catwalk boards, guardrails and guardrail posts, ladders or ladder frames, and optionally caster wheels for mobile towers.
What standards does your frame scaffolding meet?
Frame scaffolding is manufactured to BS1139 and EN12810 standards. Our factory is ISO 9001:2015 certified with EN1090 structural certification and ISO 3834-2 welding quality certification. Mill test certificates (EN 10204 Type 3.1) are provided with every shipment. Third-party inspection by SGS/BV is available.
What is the minimum order quantity and delivery time?
Standard MOQ is one 20ft container (22-28 tons depending on product mix). Trial orders from 1 ton available via LCL. Production time is 15-25 days after deposit. Sea freight is 20-45 days depending on destination. Total door-to-port delivery is typically 6-10 weeks. Mixed container loads are supported — you can combine frames, braces, decks, and accessories in one shipment.
