摘要： Disclosed herein is a slatted screen 10 comprising a frame comprising first and second opposite side members 12 and first and second opposite end members 14. A plurality of slats 18 extend between the side members 12. The slats 18 lie in a common plane P and comprise a first and second end slats 18a at opposite ends of a plurality of intermediate slats 18b. The intermediate slats 18b comprise a first group of slats 18b1 and a second group of slats 18b2, wherein the slats of the two groups are interspersed with each other. The slats 18b1 of the first group are angled relative to the common plane P at different angle to the slats 18b2 of the second group.

摘要： Disclosed is a substantially rectangular plinth member for installation at the base of a fence to at least partially close a space between the fence and a ground surface underneath the fence. The plinth member is elongate and comprises a first major surface and an opposite second major surface. The plinth member has a major axis and a minor axis extending perpendicular thereto, the major and minor axes defining a notional centre plane of the plinth member. The plinth member has first and second end margins at its respective opposite ends along the major axis and third and fourth end margins at its respective opposite ends along the minor axis. A plurality of substantially parallel stiffening formations are defined by portions of the plinth member that are displaced from the notional centre plane, extend between the first and second end margins, and are spaced apart between the third and fourth end margins. The stiffening formations are configured such that the plinth member has a greater pressure load bearing capacity when loaded on the first major surface than it has when loaded on the second major surface.

摘要： Disclosed is a metal sheet having a first major surface and an opposite second major surface, a first end and an opposite second end, and a first side edge and an opposite second side edge. The sheet has a plurality of parallel corrugations having a length defining a first axis extending along the sheet, a width defining a second axis extending across the sheet, and a depth defining a third axis extending through the sheet. The corrugations are formed by roll forming of the metal sheet. In transverse cross section, each of the corrugations comprises a substantially convex portion and a substantially concave portion. The substantially convex and concave portions each comprise a plurality of substantially linear portions with curved transition portions therebetween. The curved transition portions have a radius sufficiently small to cause plastic deformation of the metal sheet during roll forming of the corrugations. The substantially convex and concave portions each approximate a smooth curve.
