LYSAGHT® FLEX-LOK™

structural standing seam profile is the latest addition to the LYSAGHT® suite of products. Unlike our range of architectural standing seam profile, this roofing system requires no substrate as it is profiled with structural strength to function as a single skin roof to increasa its ability in thermal resistance and sound transmission. In addition, LYSAGHT® FLEX-LOK™ can be formed into straight sheet, convex curved sheet or tapered sheet to meet increasingly sophiscated roof geomertries demanded by designers today. As such, LYSAGHT® FLEX-LOK™ is the architects, engineers and contractors' ultimate choice for roofing solution.

LYSAGHT® FLEX-LOK™ provides variety of material that can be used to create individual, modern building facades and imaginative roof landscapes.

straight

Advanteges

No fastener penetration ensures weather tightness performance.
Advance concealed clip system provide excellent uplift resistance.
Available on tapered and curved sheets to fulfill the most challenging design criteria.
Can be roll-formed on site to avoid end overlapping and to achieve. extreme length according to the project requirements.
Available in a range over widths in ferrous and non ferrous material.
Original clip design minimize the need for roofing thermal expansion joints.
Specially engineered thermal pad of the clip can reduce thermal bridging effects.
Excellent in rain drainage (high ribbed profile).
Thhe minimum roof pitch is 1.40.

1. Support must no be less than 1.5 mm BMT.

2. The fastened diameter of the seam is 20 mm, tolerance should be within-0.7mm-+0.3 mm.

3. Seaming up can be finished by twice fastening, first to diameter about 21-22 mm and then to the final size.

4. Values provided here are the strength of ultimate wind capacities.

Fixing Clips

Step 1 :

Fixing clips, FLEX-LOK™ is anchored onto the purliins with heat insulated concealed clips. Pay attention to the correct direction.

Step 2 :

Fixing male and female ribs on the clips. Place the fermale rib overlapping on the male rib from the previous sheet.

Step 3 :

Lock up (seam) the ribs using machine on site.

Installation Process

Double Skin typical use for Roofing/Walling Linier

Step 1 :

Fixing inner sheet profile substrate on the purlin with self-drilling screw.

Step 2 :

Fixing Z-subgirt on the substrate with sself-drilling screw.

Step 3 :

Fixing clips on the Z-subgirt with self-drilling screw.

Step 4 :

Laying insulation on the substrate and pressing for clip exposure.

Step 5 :

Laying LYSAGHT® FLEX-LOK™ sheet on the clip with hand seamer on the end of rib.

Step 6 :

Clamping the seamer on the end of rib and seaming aling the length of roof.

Tools & Accessories

Mechanical Seamer

LYSAGHT® FLEX-LOK™'s system seamed onto the clips using aa mechanical seaning process. The seamer consists of two seaming rolles that are clamped onto FLEX-LOK™ panel, plus four guides to ensure the correct height is maintained.

Hand Seamer

The first 200-300 mm should be hand crimped to enable the seamer to be clamped onto the sheet. The hand tool is used by squeezing the handles inward to close the seam.

FLEX-LOK™ Clips

FLEX-LOK™ Clips are extruded from structural grade aluminum. The shape of the clip has been carefully designed to minimize the strength, in both upward (wind uplift) and downward (wind, dead load) conditions. The head of the clips accurately matches the FLEX-LOK™ sheeting to ensure the sheets slide freely during thermal movement.
