🏗️ Uses of TR-90 sheet

• Roofs of industrial buildings

• Warehouse and warehouse ceilings

• Covers for shopping centers and large format stores

• parking lot roofs

• Covers for industrial plants and maquiladoras

• Large span metal structures

• Roofs with low or medium slopes

• Rehabilitation and replacement of existing roofs

✅ Advantages for these uses

• Allows clear wider gaps than other profiles.

• Buena structural load capacity.

• Excellent storm water drain.

• Compatible with isolated systems such as insulpanel, insulfoil or mattress.

Nominal thicknesses of base steel according to N3 ETP MEXUNI P05 AG Gauges.
Tolerance ¾ ASTM
Theoretical Weights +/- 7%

1. * Recommended maximum separation between support for a load 100 kg in the middle of the class.
2. ** Recommended maximum spacing between supports for two loads of 100 kg to clear thirds.
3. Wind suction loads may be increased by 33% for being accidental load.(Consult local building code)
4. No value exceeds a maximum deflection of L / 240.
5. The properties and load capacity were calculated for an ASTM A-653 grade SS steel. 37 (Fy = 2600 kg/Cm2, Fb= 1560 Kg/Cm2)
6. Important note: Due to its very sturdy structural sheet characteristics, this ribbed is not calculated according to the conventional method of reduced compression areas of the AISI design manual. The load capacities were obtained through load tests also accepted in said manual.
7. Projects must be calculated by an Engineer responsible for it to satisfy the codes, standards and procedures accepted by the construction industry.
