A method and an extrusion or pultrusion device for forming a profile product made from a material in a production direction, said device comprising a rotating die, extending in a radial direction and a width direction, having two opposite first and second side walls and an outer circumferential surface extending in the width direction therebetween, wherein the rotating die comprises a first side portion in connection to the first side wall and a second side portion in connection to the second side wall and a mid-portion extending between the first and second side portions, and a profile definition zone having a longitudinal direction coinciding with the production direction, a height direction and a width direction being perpendicular to the height direction, comprising a through channel comprising a first channel section followed by a second channel section downstream the first channel section with reference to the production direction, wherein the rotating die is rotatable about an axis extending across the production direction and arranged to allow the outer circumferential surface to, while the rotating die rotates, exert a pressure onto a surface of the material when fed through the profile definition zone.

A mounting bracket (50) comprises a non-planar structure shaped by bending one or more portions of a planar body, wherein the planar body comprises before it is formed into a planar body a two-dimensionally profiled load-path approximated lower-mass structure. The planar body may be a blank stamped from material sheet or a slice separated from a profiled material block. The two-dimensionally profiled planar body may be iteratively designed using load-path analysis taking account of functional regions and preserve regions. The bracket may be used as load support for wall and roof cladding installations that require a large number of support brackets.

Tread members for climbing products are described herein that have indented treads that may provide enhanced grip and/or improved slip resistance. The treads are formed on a standing or other engagement surface of the tread member. In some approaches, the treads may be incorporated into an upper surface of a rung, step, platform, or plank of the climbing product. The treads include a plurality of pips or ridges extending across the tread member in a first direction. The first direction may be an extrusion direction or a lateral direction. The pips or ridges may provide slip resistance in a direction perpendicular to the first direction. The pips or ridges further have a plurality of indentations or cuts formed therein at an angle of about 5 degrees up to about 90 degrees relative to the first direction. So oriented, the indentations may provide slip resistance in additional directions.
