Welded I-beam is mainly used in the bridge large spans of industrial and other buildings (4-18 meters). As raw material for producing such beams is used as a low-alloy and carbon steel. The strength and quality in this case, guaranteed by the manufacturer, with I-beam should be made according to State standards and be certified. See KBS for more details and insights. What is a welded I-beam? Beams divided by type of section, they may be rolling or welded (composite). The use of welded I-beam allows you to reduce weight bearing structures up to 30%, compared with hot-from-behind optimum selection of the composite section. And also, there is the possibility of a cross section of different types of steel girders for the shelves and walls, making the asymmetric cross-sections, as well as to minimize waste due making the beam a predetermined size.

I-metal beams have several advantages. The first of such a beam can cut large openings with a large load. Beam is off (but remember, that at high temperatures in the beams – they lose their load-carrying capacity). In addition, it is resistant to biological attack. I-steel beams are widely used in the construction of prefabricated buildings as the carrier frame and floors, as well as to create runways for passing crane-girders. Using the I-beams with variable cross section provides a high efficiency of internal volume of the building and significantly reduce operating costs. The disadvantages of I-beams welded include their susceptibility to corrosion, in the absence of a protective coating and the presence in the building of aggressive substances. Installation of beams is impossible without special equipment.

Sandpit for the children with their hands The whole procedure consists of 8 stages. Consider them: Step 1. Determined sketch with the dimensions of the future sandbox. We do 1400h1400 mm. Height of 1800mm is better to make that adults can freely play with child. The roof itself needs to be done more widely in order to not fall rain.

We do 1800h1800 mm. Height 600mm (1 / 3 of the width). The roof will strengthen to 4 column at the corners. Such a design is the most stable and robust. Step 2.

Material select material Softwood natural drying of living twigs. We need: – ten 150h25h6000 mm – 6 pcs. – Board 150h50h6000 mm – 3 pc. – Timber 100h100h2000 mm – 4 pcs. – Plywood water-resistant 1500h1500h20 mm – 1 sheet – wood screws 4h55mm – 200 pcs. and 5h90 – 50. Step 3. Tools manufacturing at home, we need: saw, jigsaw, planer, screwdriver or screwdriver, hand cutter, tape measure, carpenter's square, pencil. Step 4: Base. Photo 1. Step 4: Base. Photo 1. Step 4. Base We make billet base. Cut off 4 boards 50mm, length 1500mm (with a margin, then the excess can ottortsevat). Prostrogaem from all sides planers. Tortsuem in the size of 1400mm and 45 cut corners on the ends. Choose the lower edge of a quarter of the thickness of the plywood. Twisting the box base screws 5h90. Cut the plywood to size and fasten to the bottom screws 4h55. Base ready! Step 5.
