"The trellis Al made for screening our pergola was everything I wanted it to be.  It was a competitive price, done within a very good time frame, and was of an extremely high quality.  I couldn't have built this to the same standards at anywhere near the same price and within the same time as Al did.  I'll get all of my trellis from him in the future." ​Steve K, March 2019

FREQUENTLY ASKED QUESTIONS

Anything else you need to know, please get in touch!

WHY USE MACROCARPA TIMBER?

Macropcarpa is a great enviro-friendly alternative to treated timber.  It is naturally durable because it has natural oils that deter insects and fungal growth. So it can be used without having to resort to the toxic trio of copper, chromium and arsenic (chromated copper arsenate or CCA) with which radiata is treated to achieve the same durability. The enviro-friendly radiata option is MicroPro treated which we use, and you can read about on this page. It is a low- to medium-density softwood that looks and works like kauri. Its durability, especially in larger-sized pieces, and its eco friendliness make it popular for raised garden beds and compost bins.  Macrocarpa has very good dimensional stability—better than radiata which means it will swell and shrink less in response to atmospheric humidity.  Above ground the heartwood timber should be sound for 20 to 30 years (macrocarpa has very little sapwood).

WHY USE MICRO-PRO TREATED PINE?

MicroPro is an Environmentally Preferable Product. It was the first wood treatment process to receive EPP Status. MicroPro technology is the first treated wood process to be certified by Scientific Certification Systems (USA) as an Environmentally Preferable Product (EPP) based on a life cycle assessment. You can read about it's EPP credentials hereMicroPro® technology is a revolutionary way to pressure treat timber for most end uses including landscaping, decks, fences and general construction.  MicroPro uses micronised preservatives to penetrate the timber which provides a number of consumer benefits, in addition to protection against fungal decay termite and borer attack, better corrosion performance, lighter colour and compatibility with aluminium building components.  MicroPro pressure treated timber products are protected from termites, borers and fungal decay, and are backed by a Limited Guarantee*.

IS YOUR TIMBER TREATED?

We use untreated macrocarpa from Southland and the advantage is that this timber does not require any treatment. It is naturally durable for above-ground purposes.

We also use Micro-Pro treated Select-grade pine which is an Enviromentally Preferred Product (EPP). You can read more about this above.

CAN YOU DELIVER?

Yes, we have delivery options available for the greater Christchurch area, or you can pick up from the yard. For orders outside the greater Christchurch area we can arrange suitable transport at your cost.

DO YOU INSTALL?

Yes we do offer an installation service. We are experts at what we do and it doesn't cost the earth to have your installation done professionally. We concrete all posts that go into the ground to ensure a more solid and durable structure.

PAINT OR STAIN, WHAT WORKS BETTER?

Macrocarpa has a fine grain and machines and sands well to give a high-quality finish. When dry, macrocarpa will accept a variety of paints, oils, two pot resins and varnishes. For exposed areas it is best to stain. The advantage is that it does not peel and can then be re-stained without much treatment. Painting is okay for sheltered areas. Keep in mind to re-paint before the paints starts cracking or peeling. You can also leave the timber bare – the timber will get a nice silvery / grey look over time and it can still be stained later if you wish.

The recommendation for MicroPro EPP treated pine is to follow the manufacturer’s instructions and label of the finishing product, If you desire to apply a paint, stain, clear water repellent, or other finish to your preservative treated timber. Before you start, we recommend you apply the finishing product to a small exposed test area before finishing the entire project to insure it provides the intended result before proceeding.

HOW LONG DOES IT TAKE TO MAKE?

Our macrocarpa standard trellis and any custom trellis will be manufactured to order.  Please expect approximately 7 to 14 days for delivery.  We do carry standard trellis sizings in stock for MicroPro treated EPP Pine.  For other custom structures and installation our delivery time can vary.
