The Zamil Steel MaxSEAM roof system is one of the strongest and most weather-tight standing seam roof systems available in the industry today. The 360 deg. 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.
The MaxSEAM roofing system acts as a monolithic membrane that completely protects your building. It is the most recommended roofing system for tropical, rainy, snowy or high wind (cyclonic) regions.
Using the Zamil Steel SuperSEAMER machine, the side laps of adjacent panels are seamed together creating a 360 deg. double lock seam, which has machine-applied mastic to ensure a secure, weather tight leak-proof joint.
To further improve the weather-tightness of this roofing system, the end laps may be eliminated by rolling MaxSEAM panels on site, using a mobile roll former. Standard MaxSEAM panels (rolled formed in the factory) have a maximum length of 11.5m, while Panels rolled on site can achieve a length up to 100 meters*
*Depending on the project size and requirements, please consult a Zamil Steel representative for onsite roll forming and panel length more than 50m.
| Why Use MaxSEAM for your Roof? |
Standing Seam Roofing systems (SSRs) have been one of the most exciting breakthroughs in roofing technology in the last 25 years. For the past few years, they have been widely used in almost 50% of all low-rise commercial, industrial and institutional buildings across United States. SSRs have proven to be the most efficient, effective and value for money roofing systems for rainy, windy and tropical regions.
MaxSEAM assures adequate drainage from rain and snow. Designed as a water barrier, the raised seam assists drainage; the end laps, inside closure, outside closure, tri-bead mastic, along with the machine-applied sealant (inside the seams), increases the lap tightness further.
The fastening system of MaxSEAM is designed to handle the potentially damaging effects of thermal movement (especially heat expansion). The ArtiFloat clip, that locks the panels in place, is concealed inside the raised seam. It is a unique clip with a moveable feature allowing the panel to expand and contract with temperature changes, i.e., giving the roof surface a “floating” action. The concealed clip system also results in fewer through-roof fasteners, minimizing the probability of leakage.
The life cycle cost of the MaxSEAM roofing system is lower than any other steel panel roof system. Using Zincalume coated steel, its life expectancy is longer where less maintenance is required.
MaxSEAM carries UL90 Uplift ratings, covering a wide range of installation procedures. MaxSEAM has met all test requirements as specified in CEGS 07416 Standing Seam Metal Roofing System Guide Spec.
| Begins and Ends in a High |
Unlike most other SSR systems, the gable, at both ends of the roof, finish with a 76 mm high standing seam, avoiding finishing in the low, flat part of a panel where the greatest possibilities for leaks occurs.
MaxSEAM has been tested under ASTM E1646 “Standard Test Method for Water Penetration through Exterior Metal Roof Panel System” and ASTM E1680” Test Method for Rate of Air Leakage through Exterior Metal Roof Panel System”
MaxSEAM has achieved approval from FM Global as a Class 1 Roof Panel. Under the same certification, MaxSEAM meets Class 1-SH hail damage requirements and Class 1A Fire Classification when installed at a maximum roof slope of 5 in 12 (42%).
MaxSEAM panels are available in 0.54 mm Zincalume coated steel. Zincalume is a corrosion resistant alloy that comprises of 55% aluminum, 1.6% silicon and 43.4% Zinc. Fasteners are metallic-polyester coated heat-treated carbon steel fasteners assembled with galvanized steel washers bonded with EPDM seals,.
It is no wonder that MaxSEAM is fast becoming the preferred roofing system for a growing number of commercial, industrial and institutional buildings.
ArtiFloat : The Clip That Eliminates Binding and Friction
Zamil Steel’s MaxSEAM distinguishes itself from the many types of standing seam roofing systems available in the industry with the special ArtiFloat clip, that articulates and floats at the same time. The introduction of this clip to the system not only eliminates binding but also friction.
| The ArtiFloat clip comprises of three main sections; the base, intermediate and top section. |
Binding on the clip is primarily attributed to misalignementor out-of-squareness of purlins or joists. Binding would restrict the standing seam from properly floating the way it was designed, i.e., along the width of the building. The four-piece ArtiFloat clip articulates between the base section and intermediate section of the clip thus eliminating binding.
In most clip systems, the top portion of the clip moves whereas the base remains fixed. This creates friction and drag between the clip and the panel, greatly restricting movement. The ArtiFloat clip allows for 60 mm of slide per clip and supports both the top and bottom of the male leg of the panel eliminating friction and allowing the panel to float freely as it was designed.
| Panel Specifications and Properties |
MaxSEAM Steel Panels conform to ASTM A729M Grade 345B and is coated with a protective layer of Zincalume, which is 55% aluminum, 1.6% silicon and 43.4% Zinc alloy coating (150g/m2 on both sides).The steel panels are available in 0.54mm (nominal) bare Zincalume or 0.58mm (nominal) Frost White, XRW pre-painted Zincalume. Please refer to Zamil Steel representative for extended deliveries on non-standard colors and non-standard coating systems (XPD or PVF2)

Using the Zamil Steel SuperSEAMER machine, the side laps of adjacent panels are seamed together through a mechanical action, creating a 360 deg. double lock seam, which has a machine applied mastic to ensure a secure and weather tight leak proof roofing system.
The MaxSEAM mobile roll former is available if endlaps are not preferred in the roofing system. The roll former weighs approximately 3.5 MT and can be transported to most jobsite via a container. With a roll forming capacity of between 12-15m per minute, MaxSEAM panels can be roll formed on site as a continuous panels for up to 100m.*
*depending on the project size and requirements, please consult a Zamil Steel representative for onsite roll forming and panel length more than 50m.
MaxSEAM roofing system is installed on site using a field seamer, SuperSEAMER.
After pre-seaming of the start of the panels using a Seaming hand tool, the SuperSEAMER is then fitted on to the pre-seamed panel, adjusted and locked, before the rollers are activated to start the complete electric seaming process. With the simple quick release handle, a very short time is required to move the SuperSEAMER from one seam to another. Weather-tight 360 deg. seams are made without affecting the panel paint finish.
Zamil Steel has appointed Authorized Installers of MaxSEAM (AIMs) among its Certified Builders who are adequately trained and experienced and possess the necessary tools install MaxSEAM. Zamil Steel strongly recommends that all its MaxSEAM roofing systems be installed only by one of its AIMs. Contact Zamil Steel for the latest list of AIMs in your region.
