Galvanized roof sheet carbon steel storage building(LWY-SS255)
As a new form of construction option and emphasize on steel frabrication,Galvanized roof sheet carbon steel storage building(LWY-SS255) is mostly made up of steel column,steel beam, steel truss and other steel components which are crafted by profile steel and steel plate.The connection way mainly adopt welding,bolts and rivets.The cladding system apply for corruaged steel sheet and sandwich panel
For Galvanized roof sheet carbon steel storage building(LWY-SS255) without the floor support plate
Main structure:steel column,steel beam,column bracing,wall and roof purlin,horizontal bracing and other supporing steel components.It usually goes for H sectional steel,C or Z profile steel and other profile steel member.
A:Craftship of main structure components-steel column and beam:CNC flame cutting-H bean assemblage-SAW welding-Riveting and welding parts
Surface treatment:painted or galvnised treatment.Whether painted or galvanised,the steel components need to go through shot blasting processing firstly.
There are 3 times of painting when adopting painted option-primer,intermediate coat and topcoat.They refer to epoxy primer,polyurethane coating and acrylic polyurethane topcoat to perform out the magnificant anti-corrasive property.
Galvanised process:Another better option is galvanised surface treatment.It devides into 2 kinds of galvanise treatment-electrogalvanising and hot-dip galvanising.
B:craftship of main structure components-roof and wall purlin(C/Z profile steel),column bracing,horizontal bracing and other profile steel components.Also there are usually 2 kinds of surface treatment-painted or galvanised.
When it comes to the production of C/Z profile steel or other profile steel components,the follwing procedures are involved:
blowing
flattening
forming
stereo stype form
strengthening
length measurement
flush the lacing hole
flush ellipse connecing hole
final forming and cutting
The following charts are the specification of C/Z profile steel.
2.Cladding system:
For Galvanized roof sheet carbon steel storage building(LWY-SS255) ,the wall and roof cladding system apply for corrugated steel sheet and sandwich panel:
A:For sandwich panel,therer are several kinds of sandwich panel:
Polystyrene panel,
glass wool sandwich panel,
rock wool sandwich panel
PU panel.
Thickness is usually 50mm,75mm and 100mm
b:For corrugated steel sheets,here are the common used rib style of steel sheets:
3.Installation of Galvanized roof sheet carbon steel storage building(LWY-SS255):
I.Installation of steel column:
II.Installation of steel beam:
Installation of wall and roof purlins and other steel components:
Wall and roof cladding system installation:
Packaging & Shipping
Packaing:The Galvanized roof sheet carbon steel storage building(LWY-SS255) package is nude cargo but Longwanyuan shall accompany steel structure compoments with cotton blanket on certain parts to prevent the components from collision.(like shown in the picture)
Shipping:
For the Galvanized roof sheet carbon steel storage building(LWY-SS255),the shipping is usually with 20ft/40ft shipping container.Longwanyuan shall assign a special team work on the loading to the shipping container in order to put each components in right position and minimum the collison damage during the shipping.
For the Galvanized roof sheet carbon steel storage building(LWY-SS255) with Floor Support Plate
A.The floor support plate apply for the multi-storey prefab light steel structure building usually adopts galvanised steel plate cold-formed to make the section into V/U/Trapzium shape then into contemporaty application.
