A large part of China's railway bridges use simply supported T-shaped beams, and sidewalks are set up on both sides of the bridge deck for railway maintenance personnel to walk. The sidewalk adopts the form of steel bracket, which is composed of angle steel welding or splicing, and is fixed to the ballast retaining wall of the bridge deck by pre-embedded U-shaped bolts or pre-embedded T-shaped steel. Reinforced concrete sidewalk steps are laid on the bracket. The construction process is more complicated, and the later maintenance and repair work is heavy. The new sidewalk steel beams produced by Anyang Railway Equipment Co., Ltd. are mainly used for passenger and freight railroads with a speed of 160km/h and 200km/h, which can simplify construction, increase bearing capacity, and facilitate later maintenance. Steel beams in non-sound barrier areas: mainly composed of lower flange plates, webs, upper flange plates, railing column foundations, railing columns, studs, rubber pads, railing round bars, railing angles and bolts. Steel beams in the sound barrier areas: mainly composed of lower flange plates, webs, upper flange plates, sound barrier column foundations, railing columns, studs, and rubber pads. Steel Beam Production Processï¼? cutting---leveling---welding---shot blasting---Co-infiltration---cleaning---passivation ---sealing---packing Surface quality There should be no welding slag, spatter, burr, etc. on the surface; the technical requirements of the welding part should meet the design regulations. When there is no specific stipulation, the technical requirements of the welding part should meet the requirements of Appendix G in Q/CR9211, and the welding non-destructive test should be in accordance with JB/ T6061 stipulates to proceed. Anti-corrosion layer of steel beam Except for railing posts, railing angles, railing steel bars and bolts, the rest of the steel beams are treated with composite infiltration layer technology for anti-corrosion treatment (multi-element powder co-infiltration after welding + passivation without heavy metal element passivation + sealing treatment) . Anti-corrosion layer for sidewalk railings and bolts Sidewalk railing posts, railing angles and bolts are treated with multi-alloy co-infiltration for anticorrosion treatment, which meets the relevant regulations of TB/T3274. Rubber pad The rubber backing plate is made of EPDM rubber raw materials, and regenerated rubber is forbidden.

The sunflower seed is the fruit of the sunflower (Helianthus annulus). The term â??sunflower seedâ?? is actually a misnomer when applied to the seed in its per carp hulls. Botanically speaking, it is a cypsela. When dehulled, the edible remainder is called the sunflower kernel or heart. It is a tall, erect, herbaceous annual plant belonging to the family of Asteraceae, in the genus, Helianthus. Its botanical name is Helianthus annulus. It is native to Middle American region from where it spread as an important commercial crop all over the world through the European explorers. Today, Russian Union, China, USA, and Argentina are the leading producers of sunflower crop. It produces grayish-green or black seeds encased in tear-dropped shaped gray or black shells that oftentimes feature black and white stripes. Since these seeds have a very high oil content, they are one of the main sources used to produce polyunsaturated oil. Shelled sunflower seeds have a mild nutty taste and firm, but tender texture. Their taste is oftentimes compared with the Jerusalem artichoke (not to be confused with the bulb artichoke), another member of the Helianthus family. Sweet, nutty sunflower seeds are an excellent source of essential fatty acids, vitamins, and minerals. Sunflower kernels actually employed to extract edible oil at commercial levels. Besides being eaten as popular snacks, they are also used in the kitchen to prepare variety of recipes. Specification of Sunflower Seeds: Crop Current Year Origin EU Grade Premium Mean Of Selection Machine Cleaned Purity 99% Min. Moisture 7.5% Max. Admixture 1% Max. Imperfect 1% Max.
