Layher Blitz material list: a 10 m facade worked through

Which bay lengths does Layher Blitz come in?

Layher’s German assembly and use instructions describe Blitz as a steel frame scaffold built from prefabricated parts, 0.73 m or 1.09 m wide, with bay lengths of 1.57, 2.07, 2.57 and 3.07 m and short lengths of 0.73 and 1.09 m. The frames are 2.00 m high, which fixes the distance between deck levels at 2 m (Layher Blitz instructions, edition 11.2013, chapter 1). Layher offers its current assembly and use instructions in the downloads area of its own site; the edition quoted throughout this guide is 11.2013 (article no. 8102.030), read from a copy hosted by a German retailer, so check the current edition before you build.

The German approval for the steel system, Z-8.1-16.2 of 2 January 2025, valid to 4 January 2030, sets the envelope for the standard configuration: bays up to 3.07 m for working scaffolds of load class 3, with the top deck no higher than 24 m plus the spindle extension (DIBt Z-8.1-16.2, Annex B, B.1). Load class 3 means a uniformly distributed load of 2.00 kN/m², roughly 200 kg/m²: the approval refers to EN 12811-1, Table 3, and Layher’s own marking example in the instructions gives the same figure (Blitz instructions, chapter 1). It is the class for most painting, rendering and repair work. Anything heavier, or a configuration the approval does not cover, needs its own calculation.

So the menu for filling a wall is short: four standard lengths, two short ones, and one frame height. That is what makes Blitz quick to count, and also why some wall lengths fit badly.

How do you fill a 10 m facade with Blitz bays?

The scaffold normally has to run a little past each end of the wall, so the last metre of render or paint can be reached from a full bay rather than from a ladder. On a 10 m wall the options look like this:

Three long bays leave the wall ends uncovered. Four long bays reach 2.28 m past the wall, which is useful if the scaffold has to turn a corner or carry a stair at one end, and wasteful if it does not. The mixed layouts hit the length almost exactly, but every bay length you add is another deck, guardrail and toe board size on the delivery note.

The piece count moves with the layout. In ScaFix’s engine, a straight 8 m high wall in four 2.57 m bays needs 122 pieces for 79 m² of scaffold, while three 3.07 m bays, which leave the wall ends uncovered, need 101 pieces for 71 m². The fifth frame line costs two more base jacks, another set of frames and two more ties, and the shorter decks are lighter to hand up.

The engine’s list: four 2.57 m bays, 8 m high

Parts list: Layher Blitz, 10.28 m × 8 m

One straight wall, 10.28 m long and 8 m high, in 4 bays (4 × 2.57 m), 0.73 m deep, decks at 2.71 m, 4.71 m, 6.71 m m: 79 m² of scaffold and 122 pieces in total, computed by ScaFix’s engine.

Fixed example computed by the app’s engine: no corners, openings, sheeting, hoists or loading bays. The manufacturer’s assembly instructions decide; this is planning, not structural approval.

What is on each line of the 4 × 2.57 m list?

Why twelve ties?

The approval allows three anchor patterns: 8 m staggered, 4 m continuous and 2 m. In the 4 m continuous pattern every frame line is tied at vertical intervals of 4 m and every standard in the top lift is tied, although every second one may be left out if the level below is tied (DIBt Z-8.1-16.2, Annex B, B.5). ScaFix reads that rule strictly: two anchor levels, five frame lines each, plus one V-tie per level that resists forces along the facade. The approval forbids V-ties on the outer frame lines. Ties go close to the node where frame and deck meet, and an anchor level may sit at most 30 cm off the node. The three-bay version has one frame line fewer, so it lists 10 ties.

What changes at four bays and 10 m?

Keeping the long 3.07 m bays and going to four of them, 10 m high, gives a scaffold with 2.28 m to spare, the version to use when the run has to turn a corner.

Parts list: Layher Blitz, 12.28 m × 10 m

One straight wall, 12.28 m long and 10 m high, in 4 bays (4 × 3.07 m), 0.73 m deep, decks at 2.71 m, 4.71 m, 6.71 m, 8.71 m m: 119 m² of scaffold and 158 pieces in total, computed by ScaFix’s engine.

Fixed example computed by the app’s engine: no corners, openings, sheeting, hoists or loading bays. The manufacturer’s assembly instructions decide; this is planning, not structural approval.

How does the 4 × 3.07 m list at 10 m compare?

Length goes from 10.28 to 12.28 m and height from 8 to 10 m, so the scaffold area goes from 79 to 119 m², while the piece count goes from 122 to 158. Per square metre that is better, about 1.3 pieces against 1.5, because fewer, longer bays need fewer frames and posts per metre. The ties rise from 12 to 18, because a fourth deck level brings a third anchor level, each tying five frame lines plus a V-tie.

What does the parts list not include?

A computed straight wall is the core of the order, not the whole order. Plan these separately:

• Corners. Swivel couplers, corner decks and the uplift pinning are covered in our guide to scaffold corners and returns, and the Layher Blitz system page shows them on a whole house; the quantities by wall size guide shows how straight-wall counts grow with length and height.
• Brackets. 0.36 m brackets may go on the inside on every lift; on the outside, 0.36 or 0.73 m brackets are allowed on the top lift only, and the 0.73 m bracket needs a transverse brace unless it is the reinforced type (Z-8.1-16.2, B.12).
• Access. The approval prefers a single-flight stair tower over an internal ladder (B.9). A stair is a separate set of parts.
• Netting and sheeting. The instructions warn that a scaffold clad later must have its anchor pattern completed, and the 2 m pattern ties every node for high wind loads such as tarpaulin sheeting (Blitz instructions, chapter 6). Sheeting can double the ties in the list.
• A hoist. Above 8 m deck height Layher says a builder’s hoist should be used for erection and dismantling, unless the scaffold is no more than 14 m high and no more than 10 m long (Blitz instructions, chapter 5). The 8 m high lists above have their top deck at 6.71 m, so the rule does not apply to them. The 10 m high list has its top deck above 8 m and a run of 12.28 m, longer than the 10 m exception, so it needs the hoist.
• Transport, sole boards, fan guards and loading bays. None of these are in an engine list for a plain wall.

How do UK and US rules sit on top of the list?

In Great Britain, HSE’s position is simple: proprietary system scaffolds must be erected and tied according to the manufacturer’s instructions, anything outside them needs a design by a competent person, and the scaffold is inspected after installation, at intervals of no more than 7 days, and after anything that could affect it, such as high winds (HSE scaffolding guidance). A Blitz list built from Layher’s instructions is therefore the right starting point for a British job; TG20 applies to tube and fitting, not to Blitz.

In the US, 29 CFR 1926.451(c)(1)(ii) requires ties on supported scaffolds taller than four times their base width, repeated every 20 feet (6.1 m) or less for scaffolds up to 3 feet wide and every 26 feet (7.9 m) or less for wider ones, and at horizontal intervals of no more than 30 feet (9.1 m), unless the manufacturer’s recommendations say otherwise (29 CFR 1926.451). A 0.73 m Blitz frame is about 2.4 feet wide, so the 20-foot figure applies, and Layher’s own 4 m pattern is denser than that minimum. The same section puts the top rail of a supported scaffold between 38 and 45 inches above the platform. More on the US rules is in our OSHA guide.

The fixed packages for 2 × 4 m, 4 × 4 m, 4 × 6 m and 8 × 8 m Blitz walls are on their own pages, for example Blitz 12.28 × 4 m and Blitz 24.56 × 8 m, and the Layher Blitz system page shows the same engine on a whole house. ScaFix is a planning tool that turns wall dimensions or a PDF drawing into a 3D scaffold and a parts list for many systems; it is not a structural calculation.

This is planning information, not structural approval. Layher’s assembly and use instructions and the approval Z-8.1-16.2 decide how Blitz is built and tied, together with HSE guidance in Great Britain and 29 CFR 1926 Subpart L in the US, and a competent person must inspect the scaffold before use.
