Self-drill fasteners are designed for metal-to-metal attachments of panels to steel purlins in medium and heavy gauge applications.

Self-drilling fasteners are designed to eliminate separate drilling and tapping operations for faster installation in wood-to-metal applications. It features eliminates costly pre-drilling of wood and used with steel up to 5/16″ thick.

Shackle protected padlocks are made up of brass. It works on ball-bearing locking mechanism. The body is constructed from nickel-plated solid brass with a satin finish. It is a triple-plated hardened steel shackle. It provides tough bolt cutter and hacksaw resistance.

Shelves are used to store items packed in totes, boxes, or cases. It is available in different dimensions and materials. Dimensions include weight capacity, depth, length, height, width, and diameter. Materials include aluminum, composites, plastic, steel, and wood. It is also available with various features like fireproof, outdoor-rated, portable, waterproof, corrosion resistant, and chemical resistant.

Single ply roofing is a process, which is partially adhered with either hot asphalt or adhesives. Single ply roofing generally composed of three to four basic components such as insulation, single ply membrane, flashings and adhesive. The insulation provides stable substrate for roof system. Single ply roofing membrane is a product, which combines the usefulness and universal utilization of both science and technologies.

Site Clearing is the removal of trees and vegetation on a site. Clearing operations are necessary before undertaking earthmoving operations. Site clearing gives rise to the problem of sediment discharge particularly during periods of heavy rainfall. With the removal of the natural vegetation cover, the ground surface is exposed to the elements. Heavy rains remove the sediments to the coast and subsequently destroy corals & mangroves.

Every slate roof looks terrific when it's wet - unless you're seeing leaks inside. There are, fortunately, some better ways to look at and think about this material. Slate roof failures result from breakdown of the material itself, from poor installation, or from poor maintenance. Evaluation of the condition of slate roofing, and estimating its remaining life considers at least these factors: type of slate - durability of the material itself, age and condition of the slates - where are we in the expected life of the material and what damage is visible, installation quality, fasteners used, evidence of repair history, quality of maintenance work, leaks - a telltale which could point to any or all of the above. Variations occur in color, thickness, surface texture, graduated sizes and varying widths. Standard slate roofs use slates 3/16″ to 1/4″ thick of one uniform length and width with square tails laid to a line in a conventional shingling pattern. Textural style roofs use rough-textured slates with uneven butts and varied thickness. Different colors and varying sizes are often used. The resulting roof has a very rustic look. Graduated slate roofs use slates which vary in size and often in thickness, with larger slates at the eaves, smaller and with less shingle exposure at the ridge. Original work graduated roofs show smooth transition among the sizes from larger to smaller as each course of slates approaches the ridge line. Where lots of repair work was done this effect may have been lost. This roof style makes the roof and building look larger and taller than it actually is.
