Two versatile panel profiles for demanding aquatic and corrosive environments
ARCPANEL DeltaMax is a high-performance corrosion-resistant insulated roofing system developed for aquatic, marine, industrial and other environments where protection from corrosion is critical.
Available in DeltaCorroCorro DeltaMax and DeltaTrimCorro DeltaMax, the range is available with either an EPS-FR or TPC insulated core, combined with a durable ceiling sheet to provide strength, thermal performance and long-term protection.
Choose the CorroCorro profile where greater architectural flexibility is required, including straight, curved and multi-curved applications, or the TrimCorro profile for low-pitch applications from 2°.
Both options provide an integrated roofing, insulation and ceiling solution, helping simplify construction while delivering reliable performance in harsh environments. DeltaMax is particularly suited to projects where humidity, salt and other corrosive conditions place additional demands on roofing materials.

Two DeltaMax profiles for demanding environments
DeltaMax is available in CorroCorro and TrimCorro profiles, combining corrosion-resistant construction with long-span capability, thermal performance and lightweight insulated panel design.
CorroCorro DeltaMax provides the greatest design flexibility, with straight, curved, multi-curved and bull-nose configurations available for projects requiring more complex roof forms.
TrimCorro DeltaMax is designed for straight roof applications where a lower roof pitch is required, with installation possible from 2°.
