TRIMDEK® 1015 is an innovative subtle square fluted steel cladding which is being widely used in most Industrial, Infrastructure, Commercial and Residential projects across the world.

Excellent Spanning Capabilities


TRIMDEK® 1015 is manufactured from high strength steel and provides excellent spanning capability resulting in better design freedom.

Long Lasting


TRIMDEK® 1015 is manufactured from Al-Zn alloy coated steel that offers excellent corrosion resistance and lasts up-to four times more than ordinary Zinc coated steel profiles.

Proven and Tested Profile


TRIMDEK® 1015 profile comes with return leg which provides extra support at the side laps of panels and assures weather tightness with specially engineered anti-capillary grooves. Troughed stiffeners in the valleys of profile prevents oil canning effect in larger spans, withstands better roof traffic and also clears rain water quickly with no stagnation of water. Due to its excellent features it can be designed even for low roof slopes.

Quick & Easy Installation


The long length, light weight and use of self drilling screws facilitate safe, easy and quick installation of TRIMDEK® 1015 1015 profile.

Improved Thermal Performance


TRIMDEK® 1015 comes with THERMATECH Solar Reflectance Technology that lowers surface temperature by absorbing lesser heat from the sun. It keeps both roofs & buildings cooler at reduced energy costs.

Profile


TRIMDEK® 1015 is a 1015 mm wide coverage profile with nominal 28.5 mm deep ribs along with subtle square fluting in the five pans at nominal 203 mm centre-to-centre. The end ribs are designed for anti-capillary action, to avoid seepage of water through the lateral overlap. The profile can be crimp curved to suit a curve radius of more than 500 mm.


Material Specification


TRIMDEK® 1015 is manufactured from COLORBOND® XRW steel, high tensile steel with minimum 550 MPa yield strength, metallic hotdipped coated with Al-Zn alloy (55% Aluminium, 43.5% Zinc, 1.5% Si ) as per AS1397/ IS15961 standards and ZINCALUME® AZ150 (min. 150 g/m2 total on both sides) with Super Durable Polyester 1072 mm COLORBOND® XRW steel* quality paint system of approved colour, suitable for exterior application conforming to AS/NZS 2728 type-4 / IS15965 class 3 of Tata BlueScope Steel make. The sheets have a total coating thickness of 35 microns, super durable JBM Magnetto polyester COLORBOND® XRW quality paint system of 20 microns on exposed surface and 5 micron reverse polyester coat on back surface and over 5 micron primer coat on both surfaces. The paint system is made of stable resin & inorganic pigments for paint durability and is lead free, making it suitable for rainwater harvesting. The steel sheets have a brand marking of the coated steel manufacturer (product details, date, mfg name, etc) on the back side at regular intervals confirming genuineness of the material.

Width: + 4 mm, - 4 mm


Maximum Support Spacing (in mm)


The maximum recommended support spacings are based on tests conducted in accordance with AS 1562.1-1992, AS4040.1-1992 & AS4040.2-1992. Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance). Wall spans consider resistance to wind pressure only. The pressure considered (in accordance with IS 875.3) is based on buildings up to 10m high, Zone 3 (Basic wind speed Vb = 47 m/s), Class A, Terrain category 3, K1 = 1.0, K2 = 0.91, K3 = 1.0, with the following assumptions made:


Roofs


Cpe = -1.20 (internal cladding spans)
Cpe = - 2.0 (single and end cladding spans)
Cpi = + 0.2

Walls


Cpe = -0.80 (internal cladding spans)
Cpe = -1.20 (single and end cladding spans)
Cpi = + 0.2

These spacings may vary for particular projects, depending on specific structure characteristics.

Penetrations will alter the flow of water on a roof. For assistance in design of roofs with penetrations, please seek advice from your nearest Tata BlueScope Building Products office.

Limit State Load Tables:


TRIMDEK® 1015 offers full benefits of the latest methods for modelling wind pressures. The wind pressure capacity table is determined by full scale tests conducted at BlueScope Steel's NATA-registered testing laboratory, using the direct pressure-testing rig.

Testing was conducted in accordance with AS 1562.1-1992 (Design and installation of sheet roof and wall cladding-Metal) and AS 4040.2-1992 (Resistance to Wind Pressures for Noncyclonic Regions.)

The pressure capacities for servicesbility are based on a deflection limit of (span/120) + (maximum fastener pitch/30).

The pressure capacities for strength have been determined by testing the cladding to failure (ultimate capacity). These pressures are applicable when the cladding is fixed to a minimum of 1.0 mm, G550 steel. For material less than 1.0 mm thickness, seek advice from your nearest Tata BlueScope Building Products office.



Walking on Roofs


Generally, keep your weight evenly distributed over the soles of both feet to avoid concentrating your weight on either heels or toes. Always wear smooth soft-soled; avoid ribbed soles that pick up and hold small stones, swarf and other objects.

Adverse Conditions


If this product is to be used in marine, severe industrial or unsually corrosive environments, ask for advice from your nearest Tata BlueScope Building Products office.

Metal & Timber Compatibility


Lead, copper, bare steel and green or some chemically treated timbers are not compatible with this product; thus don't allow any contact of the product woth these materials, nor discharge of rainwater from them onto the product. If there are doubts about the compatibility of products being used, ask for advice from your nearest Tata BlueScope Building Products office.

Maintenance


Optimum product life will be achieved if all external surface are washed regularly. Areas not cleaned by natural rainfall (such as top portion of walls sheltered by eaves) should be washed down every six months.

Storage and Handling


Keep the product dry and clear off the ground. If stacked of bundled product becomes wet, separate it, wipe it with a clean cloth and stack it to dry thoroughly. Handle materials carefully to avoid damage: do not drag materials over rough surfaces or each other, carry tools, do not drag them and protect it from swarf.

Sealed Joints


For sealed joints, use screws or rivets and neutral-cure silicone sealant branded as suitable for use with ZINCALUME® steel and COLORBOND® steel.

Cutting


For cutting thin metal on site, we recommend a circular saw with a metal-cutting blade because it produces fewer damaging hot metal particles and leaves less resultant burr than a carborundum disc.
Cut materials over the ground and not over other materials.
Sweep all metallic swarf and other debris from roof areas and gutters all the end of each day and at the completion of the installation. Failure to do so can lead to surface staining when the metal particles rust.

Non-Cyclonic Areas


The information in this brochure is suitable for use only in areas where a tropical cyclone is unlikely to occur. Ask for advice from your nearest Tata BlueScope Building Products office on designs to be used in cyclonic areas.
