Standard H-frame scaffolding on the 2026 Made-in-China index lists at US$10.00–32.00 per piece at a 500-piece MOQ for the 1219×1700 / 1930×1219 / 1219×914 mm door-frame set, with hot-dip galvanized mobile scaffold plank sets quoted at US$15.00–25.00 per piece at a 50-piece MOQ [S5][S1].
The same index shows painted 1219×1930 mm H-frames at US$10.00 per piece at a 430-piece MOQ and bulk steel walk-board planks at US$3.60–12.30 per piece at a 1,000-piece MOQ, so the 2026 retail spread for a single H-frame sits in a roughly 3× band driven by finish and order size [S7][S5]. For a frame-scaffolding package rather than a single frame, ADTO Group's 2026 listing carries US$400–450 per set for a complete frame scaffolding system including standards, ledgers, intermediate transoms and base jacks [S3].
2026 Price Spread by Product Type
The three price clusters that matter for specifiers are H-frame sets, individual frame components, and full modular systems. Door-frame H-frame scaffolding in 1219×1700 / 1930×1219 / 1219×914 mm sizes is listed at US$10.00–32.00 per piece with a 500-piece MOQ [S5]. Painted 1219×1930 mm H-frames sit at the low end of that band at US$10.00 per piece at a 430-piece MOQ [S7]. Galvanized mobile scaffold plank sets with caster wheels — the Layher-style mason narrow-frame configuration — sit at US$15.00–25.00 per piece at a 50-piece MOQ [S1][S10].
For complete systems, ADTO Group lists its frame scaffolding package at US$400–450 per set, with the supplier's published weight table covering standards from L=0.50 m (2.42 kg self-finish) to L=3.00 m (14.5 kg self-finish), and matching ledgers from L=0.60 m (2.38 kg) to L=2.50 m (9.14 kg) [S3]. The weight ladder is the easiest sanity check on a quoted price: at 2026 Q235B carbon steel tube pricing of roughly US$1,100–1,200 per ton [S9], a 14.5 kg standard has a raw-material floor near US$16, so any sub-US$20 quote on a hot-galvanized 3.0 m standard warrants a mill-cert check.
Finish Cost Differential: Paint vs Hot-Dip Galvanize
Finish is the single largest controllable cost lever on a 2026 H-frame quote. ADTO's published weight table shows hot-dip galvanizing adds 0.15–0.87 kg per component versus self-finish, a roughly 6% weight premium at the short standards rising to about 8% on the 3.0 m length, and a corresponding 6–8% price premium that widens as zinc prices move [S3].
For humid, marine, or chemical-exposed sites, that delta is recovered through service life: powder-coated H-frames carry a manufacturer-stated 3–5 year service life in normal exterior use, with the protective coating applied to both the inside and outside surfaces of the tube to slow internal rust [S2]. Hot-dip galvanized sets on the same index run a 3-year supplier warranty on lock-pin arch frames [S8]. The break-even math on a 500-piece 1219×1700 mm order is therefore roughly 18 months of additional service life to recover a US$3–6 per-piece upgrade from paint to galvanize.
Size, Weight and Standards Mapping
The dominant 2026 frame footprint is the 1219 mm (4 ft) bay width, with frame heights of 1700 mm and 1930 mm and a narrow 914 mm variant for confined interiors [S5][S7]. ADTO's standard-length ladder runs L=0.50, 1.00, 1.30, 1.50, 1.80, 2.00, 2.30, 2.50 and 3.00 m, and the matching ledger set runs L=0.60 to L=2.50 m — the standard / ledger grid is what lets a frame scaffold double as access and formwork support without re-drilling [S3].
Walk-through arch frames with drop-lock couplers (model FF-610B) on the 2026 supplier index carry a 3-year warranty and ship with different lock-pin options, but the published weight table is the only reliable cross-vendor comparison because Chinese mill output is not standardized across the 1.7 m and 1.93 m heights [S8]. For a fuller reference of the access-scaffolding category, see the scaffolding encyclopedia entry, which covers frame, modular cuplock and ringlock variants under one taxonomy.
Decision Matrix: When Frame Beats Modular Cuplock
Frame scaffolding wins on three project profiles: low-rise repetitive façades, interior fit-out with frequent relocation, and short-cycle industrial maintenance where erection time dominates labour cost. The 2026 ADTO frame-system listing cites a 20% weight reduction against coupler-and-pin scaffolding, which translates directly into faster manual handling on site [S3]. The trade-off is geometric flexibility: a frame scaffold is locked to the 1219 mm bay grid and the standard 1700 / 1930 mm frame heights, while a modular cuplock system accepts variable bay spacing and curved layouts.
For procurement, the 2026 wholesale price for a Q235B adjustable shoring prop (acrow) sits at US$6.00–7.00 per piece, ringlock system components at US$8.50–25.00 per piece, and EN74 drop-forged couplers at US$1.58–1.90 per piece [S9].
MOQ, Lead Time and Total Landed Cost
MOQ tiers on 2026 frame-scaffolding listings are tightly clustered between 50 and 500 pieces, with the 50-piece MOQ attached to galvanized mobile plank sets and the 500-piece MOQ to the 1219×1700 mm door-frame set [S1][S5][S10]. The 1,000-piece MOQ applies only to bundled walk-board planks at US$3.60–12.30 per piece [S5]. For a typical 1,000 m² façade requiring roughly 600 frames plus 1,200 ledgers, the 2026 unit-price band lands at US$6,000–19,200 for frames and US$4,500–9,600 for ledgers, with freight from Tianjin or Sichuan adding 8–15% on FOB China prices.
For projects comparing scaffolding procurement against other fabricated steel categories, the wire mesh panel price 2026 guide uses a similar MOQ-tier structure and is a useful cross-check on shipping-cost ratios. Frame scaffolding is essentially a welded-tube commodity, so the same FOB-CIF spread that drives mesh panel quotes applies here.
Failure Modes and Inspection Points
Three failure modes dominate 2026 frame-scaffolding warranty claims: drop-lock pin deformation on walk-through arch frames, internal tube rust at the powder-coating breach points, and base-jack thread wear on adjustable jacks. The published 3-year warranty on the FF-610B arch frame covers weld integrity and lock-pin geometry, not surface corrosion [S8].
For load-bearing components, ADTO's spec table is the only published reference on 2026 listings and gives the weight-per-length data that lets a buyer reject under-weight shipments: a 3.0 m standard below 14.0 kg self-finish, or a 2.0 m ledger below 9.5 kg hot-galvanized, is almost certainly produced from thinner-than-spec tube [S3]. For a complementary view on how tube-coupler standards (EN74) interact with frame-scaffold compatibility, the pipe clamp buying guide 2026 covers the drop-forged coupler specification at US$1.58–1.90 per piece that bridges frame and modular systems [S9].
Sourcing Signals and What to Track Next
Two 2026 signals are worth tracking: the Sichuan Taishenglanrue galvanized mobile scaffold plank set has held US$15.00–25.00 across the past six months at 50-piece MOQ, suggesting a stable zinc-coated sub-segment, while Tianjin Friend Steel Tube's bundled walk-board plank at US$3.60–12.30 is the widest spread on the index and the most negotiable line item at high volume [S1][S5]. A third signal: the ADTO US$400–450 frame-system price has not refreshed since the March 2026 listing, so a Q3 2026 RFQ should explicitly request a re-quote against the Q2 2026 zinc and hot-roll coil benchmarks [S3].
