T5 type stair treads welded fixing, anti-slip nosing stair treads t5 type stair tread is fixed by welding and with anti-slip plate nosing 1. T5 type stair tread material: mild steel (low catbon steel) or stainless steel 2. Types of steel grating for t5 type stair tread: -flat type: the most widely steel grating. -serrated type: with better no-slip. -"i" type: on the surface, path and items not in the same flat.with the character of light weight, economic and practical. 3.t5 type stair tread surface treatment: untreated, painting , powder coated or hot dip galvanizing 4.t5 type stair tread welding procedure: edge bars and attachments are welded with a minimum 3mm fllet weld to one side of: -every 5th load bar on series 30 grating -every 4th load bar on series 40 grating -every 3rd load bar on series 60 grating -full weld:weld one side of every load bar. -seal weld: weld both sides of every load bar.

Heavy duty type magic grating describtion: -allows a safe passage for baby carriages, wheelchair and human beings. Besides the triangular structure endures the rotations and impacts of heavy duty vehicles very well. - durable magic grating with triangular structure minimizes safety accidents and economical loss for replacements. (magic has 1.5~2 times of performance load than the common.) - main reason of grating breakage in harbor is rotary impact made by rear wheels. - magic grating consisted of triangular structure & magic bar is strong enough for rotary impact and heavy load impact. - required materials for installing of 100m of common grating for heavy load is same as that of 179m with magic grating installed. - with only use the magic grating, you can reduce 44.2% in weight directly, besides you can also save maintenance expenses due to weight lightening of materials. - the optimal load design is possible based on each load and provides safe work place when used in the plant.

1. U type trench drain grating cover introduction: use banding steel grating to design and manufacture, widely used in urban road, square, garden, docks, and airports, parking lot, highway, railway, industrial engineering and other kinds of industrial and civil architecture. 2. U type trench drain grating cover specifications: 1) u type: this model is used for cross drain type and side drain type. 2) material: low carbom steel or stainless steel. 3) standard: ybt4001.1-2007, ansinaamm, bs4592, etc. As per customer's requirement. 4) surface treatment: hot-dip galvanizing, paint or other anti-corrosive coatings 3. U type trench drain grating cover features: 1) beautiful shape: line forthright, sliver appearance, modern trend. 2) best drainage: leakage area is 83.3%, which is more twice than cast iron hot dip galvanized; rustproof force is powerful, free maintenance and replacement. 3) theft proof design: cover abd frame connecting with hinge, guard against theft, safty, and easy to open. 4) save on investment: when big span, and heavy load, the price is lower than cast iron, economizing the expenses of stolen or replacement. 5) high strength: the strength and toughness are far higher than cast iron, and can be used in as docks, airports, such big span and heavy load place. 6) more specification: meet different environment, load, span, size and shape.

Anti-rust painted walkway steel gratings for paper-making machinery Painted walkway steel grating is made of load flat steel bar and cross bar, placed horizontally and vertically, and at an equal pitch apart, by welding with 200-ton hydraulic resistance automatic welding equipment, then cutting, punching and banding ends. At last, painted finish. 1) Type of steel grating: W-pressure welded grating; L- pressure locked grating; C- socket welding grating 2) Pitch of bearing bars ranges from 15-30mm, 40mm, 60mm, 80mm, 90mm etc. with 30, 40mm recommended. Pitch of cross bars ranges from 30, 38, 50, 76, 100mm etc. with 50, 100mm recommended. 3) Sign of the shape of bearing bar: F-plain surface (F is usually can be omitted); S-serrated surface; I-the section is of "I" type. Surface treatment: G- hot dip galvanizing (G is usually omitted); P-painting; U-untreated.
