October 2018 Revision 1
Welcome to Albion Sections Ltd structural solutions for modular buildings.This booklet includes section sizes and typical details for both single storey and double storey modular buildings.
Single storey solution:Full structural calculations are available separately (on request) for the single storey modular frame comprising floor and roof cassette and corner columns. This standard design considers wind loadings which are limited to the areas shown on the attached map. It is also assumed the site is at least 2km from the sea and that the site altitude is no greater than 120m.
Corner columns, although sized, are not supplied by Albion Sections.
Two storey solution:Three solutions are provided for the first floor beam; nested solution, compound solution and single beam solution. Full details of each are provided.
These beams are designed to support the temporary roof of the lower module and first floor loadings from the upper module (floor imposed loading limited to 3kN/m2). In this case, Albion Sections Ltd do not consider wind or side sway loadings which must be considered by the client’s structural engineer.
In all cases above, the client’s structural engineer must approve and incorporate Albion Sections Ltd calculations within their design package.

Albion Standard Punchings Available
Standard round holes (diameter in mm)2, 3, 5, 7, 8, 8.5, 9, 10.5, 12, 14, 16, 17, 18, 19, 22, 25, 26, 28, 30 & 31.75.
Counterformed holes8, 14 & 18mmThis is the clear hole diameter of the counterformed hole, the distorted area is approx 2.5 times greater (critical when counterformed holes are spaced at close centres) .
Slots:Slots tools are restricted to their orientation in the section. In the following, the first dimension is with the length of the section, the second dimension is across the section.
Rounded slots:30 * 7mm7 * 30mm20 * 14mm28 * 14mm21 * 11mm30 * 22mm48 * 18mm
Rectangular slots:14 * 20
Service slot:100 * 50mm
Special restrictions on this slot:May only be punched in material 1.5mm thick or greater.
Only one slot may be formed in the width of the section.
There is no limitation on the number of slots that can be punched longitudinally.
Any series of slots may be positioned anywhere within the width of the section but all slots would be restricted to this position (i.e. slots in different positions in the section width are not possible).
Hexagonal holes:16 HEX 16mm across flats, 19mm across corners.21 HEX 21mm across flats, 24mm across corners.
Flange holes:All of the above apply to flanges as well as webs. Application limited by the width of the actual flange.
Albion Sections Ltd. Punching capability on the Bradbury machine
Restrictions / limitations on punchings:The maximum punch diameter is 31.75mm.Any non-standard punched shape (square, hexagonal) must fit into a circle of this diameter.
On any single member, as well as counterforms, 18mm*48mm slots and service slots, up to three additional different types of punching may be accommodated.
Punchings may be in singles or in pairs and different punchings can be accommodated in the width of the section.
The purchasing of tooling to punch other holes or shapes (although the limit of 31.75mm applies) may be cost effective depending on the quantity.
Manufacture is subject to our inspection and acceptance of final details drawings.
