The Porch Specialist Quality Assurance
The Porch Specialist is committed to demonstrating to customers that its oak porch kits are of the highest quality.
5 Step Quality Control Process
Your oak porch kit goes through a fully documented and auditable 5 step quality control process as follows:
1 – At point of delivery all timbers are checked against a cutting list to ensure they are correct in size and quantity and an initial visual quality check is carried out.
2 – When the frame is going into production each timber is individually checked for structural suitability and visual impact by in-house timber graders during our racking process.
3 – When the frame is being routed through production each timber is once again visually checked to ensure suitability.
4 – Prior to each job being manufactured, the machine is put through a comprehensive calibration test. The calibration of the machine is monitored throughout production by performing measurement tests for accuracy on components on average every 30 minutes.
5 – Finally, once the porch kit has been manufactured and packed it is checked off against a cutting list to ensure quality standard is appropriate and that all components needed to assemble the building are supplied.
Why our oak porch kits are a cut above the rest
We source Quercus Robur or Quercus Petraea oak for our oak frame porch kits as they consistently deliver the best quality of timber for manufacturing. They are also more competitively priced due to the sustainable way they are farmed and because these species of oak produce longer, straighter trees meaning there is a bigger volume available.
Each piece of timber is checked for any defects that could compromise the frame’s stability or strength. If a piece shows any sign of weakness, it is rejected by a certified timber grader. These graders are fully qualified and re-train yearly to ensure their skills are consistently up-to-date.
All our oak porch kits are manufactured on a state-of-the art Hundegger CNC machine. The machine is put through a comprehensive calibration test prior to each job to ensure it consistently produces high quality, accurate beams. The calibration is monitored throughout manufacture and components are checked every 30 minutes to reduce inaccuracies.
Following machining, each piece of timber undergoes further checks to ensure that it meets quality standards and the machine hasn’t uncovered any deeper defects.
While being packed for delivery, all timbers are visually checked and cross-referenced against its file and cutting list to ensure all parts of the kit are present and correct.
The Finished Product
For easy on-site assembly, all kits come complete with clear instructions and all beams are pre-drilled for fixings and pre-cut for birdmouth jointed rafters. All components are coded to assist in the assembly process.
Due to the natural moisture content of green oak, you may notice natural tannins (black marks) on your oak. These marks will naturally disappear with time. However, if you wish to remove them straight away , you can remove them with a product called oxalic acid. We recommend using Rubio Monocoat’s Tannin Remover, a ready-to-use product that removes the black stains and spots on wood caused by a reaction to acid and water.
