Designers and architects are afforded the opportunity to create a clean, glass-like aesthetic for their working entrances in order to match a fully glazed facade.   Maximizing Space The overhead sectional door slides up under the roof when opened, maximizing free space around the door opening. The overhead arrangement leaves entrances open and completely clear for product placement, or simply freeing up additional useable space.   Glazing arrangement The number of rows and columns of the "Nature Sunlight" is based entirely on the width and height of the door, which is divided equally creating the grid arrangement.   Wide range of opening As with any overhead sectional door, the "Nature Sunlight" opens vertically into the roof/ceiling, maximizing useable space in and around the opening. Running on tracks, the door rolls up and over. Track arrangements are decided by factoring the available space directly above the door opening and immediately inside the facility.   Safety Compliance The TOPSKY fully-glazed overhead sectional door is designed to meet all operational and safety requirements in the European Directives and the standards issued by the European Standardization Committee, CEN.   Under same KNSN group system, now Topsky has reached a strategic cooperation with professional steel engineering specialist namely Hangzhou FAMOUS Steel Engineering Co.,Ltd.(FASECbuildings) which is in charge of all foreign business operation of Topsky, and realized a win-win cooperation together.  Please visit our door website: www.Topsky-doors.com for more details or send us enquiry for more catelogues pickup.

High Speed Steel Mill Rolls for Hot Rolled Metal Sheet And Billet Mill Usage High speed steel mill rolls, produced by horizontal Centrifugal casting process, are all compound rolls with high speed steel as the work layer and nodular iron as the core. The material of rolls contains plenty of alloyed elements such as Mo, V, W, Cr etc. The high hardened eutectic carbides & second carbides, such as MC, M2C, M6C evenly distributed in tempered martensitic matrix, make the wear and thermal cracking resistance very excellent. Besides, the resistance to surface roughing is also good. In condition of hot rolling, the contact points between steel strip and the work rolls can form a thin adherent oxide film on the roll surface, which plays a good role in the wear features and the quality of the strip surface. FAMOUS rolls are mainly used as the work rolls in the hot strip mills and the finishing stands of bar mills; rings of the universal section mills and finishing stands of the high speed bar mills.   Usually, we make this type of roll by static cast and centrifugal cast. We recommend using centrifugal cast rolls for better performance when the groove in the roll body is not too deep. With more alloy added in, we can get a microstructure consisting of spheroidal graphite, pearlite and primary carbide type M3C up to 30%. Meanwhile, the core of the roll still keeps very strong with a great amount of spheroidal graphite in the matrix of ferrite. When the groove in the roll body is very deep, we recommend using rolls static cast with groove to achieve a low hardness drop between the body surface and bottom of the groove.   Specification:   Production Name: Forged Work Rollers  Certification: CE,BV,TUV,SGS,ISO9000 Technology: forging,open die forging,free forging,ring forging,stamping,hot,rolling Equipment: CNC Machining Centres Material: Carbon steel,Alloy steel,stainless steel Surface treatment: Heat Treatment,oxide coating,plating,finishing,painting,galvanized Model Number: Custom According to Drawings Application: Engineering Construction Machinery Chrome thickness: 25~30micron Length: 1001mm~10000mm Weight: 11kg-3200kg Tolerance: 0.01mm Roughness: Ra 0.20micron (max) Packing: Wood box for free fumigate or according to customers' requirements Shipment  Sea shipment or customized requirements,etc   Production process :   Characters:   1.

The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for re-rolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and hexagons.   Application:   The spheroidal graphite pearlitic iron rolls are widely used in the roughing stands and intermediate stands of various rolling mills.
