The 360 degree seam along the side laps of the panel; the special articulating clip, artifloat; and the carefully engineered system for strength, durability and weatherability are but a few of its outstanding features.
To further improve the weather tightness, the end laps may be eliminated by rolling MaxSEAM™ length 11.5m, while panels rolled on site can achieve a length of 90 meters.
MaxSEAM™ is also offered as an Ultimate R-roofing solution allowing for installation over an existing roof through fastened rib type roof without removing the existing panels.
Why Use MaxSEAM for your Roof?
Weather tightnessDesigned as a water barrier, the raised seam assists drainage at critical areas and, along with the machine-applied sealant (inside the seams), it increases the lap sealing to 100% tightness.
Thermal Movement
The fastening system of MaxSEAM is designed to handle the potentially damaging effects of thermal movement (especially heat expansion). The ArtiFloat clip, that holds the panels in place, is concealed inside the raised seam. It's a unique clip with a moveable feature allowing the panel to expand and contract freely with temperature changes without restraint thereby giving the roof surface a "floating" action and correcting the out-of plane sub-framing alignment to a maximum of 7 deg. The concealed clip system; a boltless connection to sidelaps also results in fewer through roof fasteners, minimizing the probability of leakages.
Cost Effectiveness
The life cycle cost of the MaxSEAM roof system is lower than any other conventional steel panel roof system. Using Zincalume-coated steel panel, its life expectancy is longer and lesser maintenance is required (Zincalume is a corrosion resistant Zinc/Aluminum alloy coating (AZM 150) that comprises approximately 55% aluminum and 45% Zinc, by weight).
Testing Credentials
MaxSEAM has been tested under ASTM E1646 -95 "Standard Test Method for Water Penetration through Exterior Metal Roof Panel System" and ASTM E1680-95" Test Method for Rate of Air Leakage through Exterior Metal Roof Panel System".
FM Approvals also certify MaxSEAM as Class 1 Panel Roofs, conforming to FM Approvals Standard 4471 (1995) with examination included simulated wind uplift pressure testing, resistance to foot traffic testing, ASTM E108 spread of flame testing, and hail damage testing.
Uplift Ratings
MaxSEAM carries UL90 Uplift ratings, tested with a wide range of installation procedures. MaxSEAM has met all test requirements as specified in CEGS 07416 Standing Seam Metal Roof System Guide Specification.
Starts and Ends with Raised Seam
Most other Standing Seam Roof systems are unable to achieve a high rib profile at gable end due to field cutting of final panel. With MaxSEAM, the gable at both ends of the roof, finishes with a 76 mm high raised seam made possible by our SuperSEAMER; thus avoiding finishing in the low, flat part of the final panel where the greatest possibilities for leaks occur.
Field Seamer and Mobile Roll-Former
MaxSEAM roof panel can be roll-formed up to a length of 90m on site by our Mobile Roll-Former to reduce the endlaps on large span structures. After which, the SuperSEAMER machine will be used to seam the side laps of adjacent panels together to create a 360 deg. double lock seam, which has a factory-applied mastic to ensure a secure and weather-tight leak proof seam.
Quality Materials
MaxSEAM panels are available in 18 inches. (457.2 mm) and 24 inch (609.6mm) width, 0.5mm and 0.53 mm thickness steel with a total of 150g/m2 Zincalume coated on both sides.
It is no wonder that MaxSEAM is fast becoming the preferred roof system for a growing number of commercial, industrial, and institutional buildings.
