1. Dense steel grating
Dense grating bearing flat-steel spacing is refers to the bonding steel than mm plate.its completely standard bonding steel plate form is beautiful,easy installation,more advantages to meet some special occasions or leak through the size of the object under strict requirements have large flow conditions,such as civil occasions,dense grating can satisfy the requirement of Ms walking shoes.then if people in industrial and mining enterprises,large demands are not allowed to have larger objects(such as 20mm diameter ball) to meet the safety requirements fall,and so on.
Dense steel grille board specifications and grades.
Standard of dense grating types and specifications of basic and bonding steel plate,dense grating grades form for:
D G 000/00/00
There after can add letter “I” or “s” with “I’ type separately bearing flat-steel bearing flat-steel or tooth type defined,detailed see steel grades of brand and specifications.my company dense spacing of steel gratings webmaster if flat for 12 or more than 20 to 30 bar spacing,more than 50 or higher requirements for the grid grille,such as shipping,offshore drilling platform,operation platform,sidewalk where,in order to prevent object fell.also used in factory workshop,aerial work platform top working platform,in order to prevent the place such as aerial falling objects.
2. Special steel grating
Special steel grating is made of serrated bearing bar and cross rods.they placed horizontally and vertically, and at an equal pitch apart,by welding with 200 ton
Hydraulic resistance automatic welding equipment then cutting punching and handing ends.
Center to center bearing bar spacing: we usually supply with 30 mm or 40mm.
Center to center cross bar spacing usually with 50mm or 100mm.and we are also pleased to accept your special order.
Product description:
1) Material: carbon steel or stainless steel
2) Cross bar pitches: maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.
3) Steel grating is made by the world first-class equipment, which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance. cross bar is pressed into the bearing bar by high tension resistance weldingring which is controlled by computer. so we can produce high quality gratings with firm welding, smooth surface and high strength.
4) Surface process of gratings: there are three types: hot-dipped galvanized ,electro-galvanized and spraying brushing and soaking. anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film will be formed on the zinc surface. it has good anti-corrosive property.
5) Packing conditions of steel grating: normally packed in pilling up ways with two pieces of square wood on both upperand bottom sides. there are four or six pieces of M10 long bolt penetrading the gratings and screwing together. it is suitable for loading and unloading by fork-lift and crane.
3. Compound steel grating
Compound steel grating is composed of chechered plate on sealed surface&steel grating with certain spanning capability.
compound steel grating is formed of any type steel grating and chechered plate in different thickness.the type FG323/40/100,FG253/60/100are generally used as base& the checkered plate with 3mm thickness is used as sealing plate.sometimes checkered plate with thickness of 4mm,5mm or 6mm is also used as sealing plate according to customer requirements.
as thermal stress may cause shape distortion after hot-dip galvanizing treatment,especially attention should be paid when choosing grating types.

5. Plug grating
Plug steel plate is a kind of bearing capacity of a certain size is larger,ordinary Q235 low carbon steel,flat steel,copper,aluminum by slotted holes,(with infixing,welding,finishing process such as manufacturing and into a steel plate products solder firm,pitch evenly,smooth surface,the design is beautiful,practical,is that supplies,and artwork.plug-and-socket steel plate is also a kind of pressure lock grille board products with bonding steel grille board of high- strength,anticorrosion,maintenance,etc,and unique characteristics so deft,uniform structure combination of precision and elegant,natural and harmonious,style refined features.in recent years,with infixing steel plate extensive application in the civil and commercial buildings,theatres,subway,passenger such municipal engineering products,high strength,corrosion with deft,mianweihu,beautiful,etc,are widely used in characteristics of civil and commercial buildings,theatres,subway,such municipal engineering field,computer trains can be used inside and outside decoration decorate condole top,and footpath,airshaft platform,advertising tablet（well,all kinds of flat,etc.）
6. Press-locked steel bar grating
Press-locked steel grating is a kind of high strength grating.it is product featuring unqique combination of uniformity and precision.it has light structure,elegant style.beautiful and natural design and it is maintenance –free.press-locked steel grating is used in civilian and commercial buildings,theatres,subway,suburban railway,and other municipal engineering.
It exhibits the same strength,long life and openness as welded grating.Material applied include mild carbon steel and stainless steel.it is also available in a serrated surface for extra safetly.
