Installation and Product Care

Installation

Create a solid reinforced concrete base (see information sheet). If not done carefully, it can create stress in the product that could damage it.

Place the two-piece frame and bolt with the supplied materials, loosely tightening all bolts. Tighten them before filling the frame with a load-bearing split.

Place the four tree grate corners on the frame, so the holes match. Install all bolts loosely first, and then tighten them.

Finish the pavement laying slightly higher than the tree grate for ideal drainage around the tree.

Corten Steel Maintenance

Corten Steel, also known as weather-resistant steel, is a steel alloy made of iron that has copper, silicon, nickel, and chromium added that is low-maintenance, weatherproof and durable. We do not recommend using Corten steel within a radius of 2 km from the coast. The Corten Steel will arrive not fully weathered, so be aware, as the Corten Steel weathers runoff may occur. We recommend the application of 'Owatoral' varnish once the Corten Steel has weathered; this will stop the product from rusting any further. 'Owatoral' varnish is available in 0.5Ltr and 5Ltr tins online.
