Metal Section Systems– Internal Partitions MS/P

StrandecTM panels form non load bearing partitions when fixed on light gauge metal sections. These partitions are fire resistant, with thermal shield and unmatched acoustics of both isolation and absorption built- in the system and panels.

Partition system choice will be as per performance requirements of fire, thermal insulation, acoustic levels, and other physical properties such as heights, thickness, weight, stiffness and expected usage patterns.

The partitions can have the natural wood strand finish or screed finish - both can be further finished by plastering, or additional veneering with other decorative materials.

 
Design Parameters
System
The choice of system will be based on the partition performance requirements – i.e height, thickness, nature of duty, fire resistance, thermal shield, acoustics and other loading factors
Components
• StrandecTM panels - tapered edge other edges available on request
• SDN- Strandec natural
• SDB – StrandecTM single side screed finished (white)
• SDC – Strandec Thermal panel
• Thickness 15, 20, 25, 30, 40 and 50mm
• Width 600mm Length 2400/1200mm
System Choices
StrandecTM Panel made from Inorganic Bonded Composites completely mineralized using Portland cement makes it as strong as wood which does not shatter or crack and is fire resistant. The matrix structure gives it strength with lightweight and also with unique acoustical and thermal insulating.

The definitive properties of StrandecTM combined with the established strengths of GI steel sections a wide range of non load bearing partitions can be assembled in a fast track construction with the added advantages of dry construction StrandecTM Metal systems perform to acoustics, stiffness and heights as per the Table.
Other Components
• Studs 50MS12 to 300MS30 depending on the design
• Tracks 50MT12 to 300MT30 depending on the design
• Deep Tracks with extra flange where required for deflection heads
• Braces - 38MB09 and 100MB12 for horizontal bracing and cross bracing to take care of axial loads and racking loads
• Screws
• Nylon Plugs
• Sound Synth
• Control Joint
• Sealants
• Glassfibre Tape
• Jointing Compound
• Glassfibre Mat as a substrate for finishing plaster where required
• Finishing plaster if required
Applications
StrandecTM partitions can be an ideal choice for various end users such as offices, schools, hotels, hospitals, industries, theatres etc
Construction Procedures
Framework
Mark the position of the partition and openings (doors, glazing, services passing thru etc). on both the floor and the soffit /ceiling. Secure the floor track and the ceiling track at not more than 600mmcentres using plugs or screws. For broader tracks secure the plugs by staggering alternatively at 300mm centres.

Place the studs of the accurate size in the floor track and the ceiling track and turn into position. Ensure that the track has enough head support. Deflection head should be placed where required. If shorter length studs are used then they should be spliced after proper overlap of at least 450mm. Studs placed at the ends should be secured to the structural member.

Horizontal bracing (if required for axial loads) to be placed on both sides of the studs with pan head screws. End studs are to be blocked using tracks as shown.

Diagonal bracing (if required for racking loads) should be secured on both sides with pan head screws as per design. Studs should be secured on either side of openings with proper headers to distribute loads above.

Additional bracing to take heavy loads should be secured at the desired locations. Services conduits can be placed in the cutouts of the studs after fixing panels on one side is completed.
Panel Fixing
StrandecTM panels of the desired thickness are to be placed horizontally with screws ( screws being at least 10mm longer than thickness of the panel ) fixed to the studs at 300mm centres vertically on the studs. (That is every stud backing the panel will have three screws one on either end and one in the centre).The panels on the opposite sides should be staggered by fixing a 300mm starter panel (easily cut at site) first at the bottom and the other standard width panels thereafter above. Control Joints are to be provided for partition runs over 7metres at every 6 metres.
Jointing
Placement of First Course – Place the starter connectors at 300mm centers with at least one on either end 150mm from the edge the edge. The second course of panels is then pressed down on the vertical wire rods of the connectors. Ensure both horizontal line and levels are maintained.
Rebar Placement
Horizontal rebar members are placed in the slots provided on either ends of the connector. The horizontal bars are to be staggered for above grade construction and on the external end for below grade construction. The bars can be clipped at every 6 feet to the connector.

Vertical rebar is to be tied to the dowels on the footing in required spacing as per design.
Braces
To ensure proper alignment of the wall formers they should be braced at the ends and at the center. The bracing should be in place on the inside face of the wall prior to concrete pour and after the wall former is assembled to a height of 1200mm.
Concrete Pour
Concrete with water/cement ratio of less than 0.60 and maximum aggregate sizes of 16mm with a slump of 120mm is poured with a line or boom pump. For additional courses the previous course should be left
rough and unfinished to provide better bond for the subsequent courses.

Control Joints are to be provided for partition runs over 6 meters at every 6 metres.
Jointing
Glass fibre tapes are placed on the centre between two abutting panels at the centre of the StrandecTM SDB tapered edge panels after filling up one coat of joint compound to hold the tape in position. The second coat is applied after the first coat is dried to cover the tape as well as the complete tapered portion of the panels on either side of the joint. The joint compound is spread to a level on both sides by a trowel.
Surface finish
The final coat a skim coat is then spread on the joint and the entire surface.
