A roofing system includes a plurality of riser blocks disposed on a support surface. The riser blocks include a group that is aligned in a row. A batten extends along the row and is supported by the group of riser blocks. The batten includes a first clip portion. A group of roofing panels is disposed along the row and is supported by the batten. Further, each of the roofing panels of the group includes a front surface, a rear surface, and a second clip portion extending from the rear surface. The second clip portion is configured to engage the first clip portion of the batten so as to secure the roofing panels to the batten.

Roofing system and method of installation

An abrasive article in form of an abrasive wheel comprising a core and a bonded abrasive body disposed within an interior recess of a peripheral surface of a core. The core comprises a polymer material and has an HDT at 0.45 MPa of at least about 130&#xb0; C., and a low shrinkage ratio.

Abrasive article having a core including a polymer material

An abrasive article has an abrasive portion with a bond and abrasive particles. A core is mounted to the abrasive portion. The core may include a plurality of segments that are interconnected to form the core. The abrasive article may include forming a plurality of core segments; assembling the core segments into a core; and then mounting the core to the abrasive portion to form the abrasive article. Forming an abrasive article may include mixing a phenolic resin, fillers and abrasive particles to form an abrasive matrix; injecting the abrasive matrix directly into a mold, such that the abrasive matrix is injection molded into a final wheel geometry; at least partially curing the abrasive matrix while it is inside the mold; and then removing the abrasive article from the mold.

Abrasive article and method of making same

An apparatus and method for producing defect-critical articles from a molding resin comprising at least 98% clear polymer and additives including a heat stabilizer and a UV blocker in an injection molding machine. According to the apparatus, there is provided an injection molding machine in combination with a molding resin. The injection molding machine's resin delivery assembly is made from a powder metallurgy formed into solid non-coated parts having a Chromium-Vanadium (Cr/V) blend. As the molding resin interacts with the resin delivery assembly, the resin only contacts the solid non-coated parts whereby the resin experiences less degradation and provides improved quality for the defect-critical articles. The method includes the steps of plasticizing, injecting, and cooling. During the plasticizing and injecting steps, the molding resin only contacts solid non-coated parts made from a powder metallurgy material containing a Chromium-Vanadium (Cr/V) blend thereby producing reduced defect articles.
