A B-shaped reinforcement beam is formed from a sheet of material to include vertically spaced upper and lower tubular sections, with a channel-shaped rib formed centrally in the unsupported portion of the front wall over each tube section. The ribs acts to stiffen and stabilize the front wall, causing the actual bending strength of the B beam to be much closer to expected theoretical values. In one form, the ribs have a vertical dimension about 33%-50% of a height of the tubular sections and a depth of about 50%-100% of the rib's height. The rib is particularly effective when the material is less than 2.2 mm, more than 80 KSI, and / or has a significant height-to-depth ratio such as 3:1.

A gutter guard for mounting on a gutter. The gutter guard comprises an elongated panel extending laterally from an inner portion to an outer portion of an underlying gutter. The panel is of undulating construction and comprises a plurality of longitudinally extending, laterally spaced, elongated raised areas for retarding the flow of rain water across the panel. The raised areas are separated by longitudinally extending recess channels. The raised areas and recessed channels have a plurality of longitudinally extending, laterally spaced rows of longitudinally spaced first holes extending through the panel to enable rain water flowing outwardly across the panel to flow through the first holes into an underlying gutter. The first holes have a narrow end portion facing the inner side of the panel and expanding outwardly toward the outer side of the panel to facilitate spreading of rain water as it travels across the panel toward the outer side thereof.

The present invention provides a crosslinked polyolefin-based resin-extruded foam sheet capable of reducing its thickness while retaining excellent flexibility and heat resistance. The crosslinked polyolefin-based resin foam sheet of the present invention is obtained by feeding a polyolefin-based resin and a thermally degradable blowing agent to an extruder, melting and kneading them, extruding the kneaded material through the extruder into a sheet to form an expandable polyolefin-based resin sheet, and expanding the sheet. Herein, a degree of crosslinking of the crosslinked polyolefin-based resin foam sheet is 5 to 60% by weight, an aspect ratio of a cell (MD average cell diameter / CD average cell diameter) is 0.25 to 1, and the polyolefin-based resin contains 40% by weight or more of a polyethylene-based resin obtained using a metallocene compound containing a tetravalent transition metal as a polymerization catalyst.

The invention relates to a continuous band for producing bags for fruit and vegetable products, formed from a continuous plastic sheet (1) which has been die-cut to produce a series of small holes (3) which are closed using mesh or net fragments (4) fixed along the periphery of said holes by means of heat-sealing, gluing or any other conventional means. According to the invention, the area of the continuous sheet (1) intended to contain the handle is provided with a transverse patch (5) of pre-determined hardness in order to reinforce the area used to hold the bag once it has been filled, such that the thickness of the band-forming plastic sheet can be significantly reduced, specifically by a value of the order of 40%, without affecting the performance of the bag in terms of mechanical strength since the area in which the greatest strains are concentrated corresponds exactly to the area containing the handle.

The present application relates to reinforced concrete columns classed in the category of reinforced concrete according to the NSR-10 and ACI-318 standards, in which the tubular channel is formed by sections with cold-roll sheets (CR) which form C-sections with a core and at least on skid which projects into the inner space of the column, coming into contact with the concrete. The skid comprises along its length a series of perforations through which concrete can pass, allowing a composite column to be formed once the concrete has set, in which steel and concrete work together and mutually strengthen their qualities to such an extent that the thickness of the sheet can be reduced, rendering the product economically viable. Moreover, the invention relates to the composite deck comprising these C-sections and a concrete core confined in the inner space of the tubular channel.
