Guides & Regulations

These are the guides we end up writing out on the phone: what the building regulations actually require, how to choose between the options, and what each decision does to the price. Written by the people who make the steelwork, in Sheffield.

We are fabricators rather than a building control body, so treat these as background rather than a ruling on your own project. Your building control officer decides what your building has to comply with.

Before you order

  • Do I need planning permission?. The usual position for balconies, balustrades, external stairs, canopies and railings, what changes it, and why your local planning authority is the only body that can tell you.
  • How to get a price from us. What to send us for an accurate quote, when a site survey is chargeable, what drawings cost, and what we do and do not supply in the way of structural calculations.
  • Lead times by product. Guide lead times for staircases, balconies, balustrades, glass, Juliet balconies, handrails, canopies and cellar doors, what the finish does to them, and when the clock starts.
  • Frequently asked questions. Surveys, drawings, lead times, delivery, installation and what we do and do not cover.

Balconies and balustrades

Staircases and handrails

  • Staircase building regulations. Rise, going, width, headroom, landings and handrails, plus UKCA marking and what building control will ask for.
  • Staircase classification. Private, utility and general access stairs, what each means for the dimensions, and which one applies to your project.
  • Steel staircase buying guide. Straight, spiral, kite winder or curved; spine or twin stringer; treads, balustrades and finishes, and what actually drives the price.
  • Steel staircase FAQs. Lead times, access, trial builds, supply only against fitted, and the practical questions.
  • Handrail building regulations. Handrail heights, when one is required, grip and diameter, ramps, external rules, materials and loadings.
  • Curved, raked and cranked handrails. Ramp and winding path handrails, twin rail systems, curved stair and balustrade rails, and what we need from you to quote one.

Glass

Garden and outdoor

Product FAQs

Finishes, materials and certification

  • Material finishes and quality standards. Galvanising, powder coating and stainless steel: what each finish does, and what is and is not a defect.
  • Natural wood. How solid timber behaves in service, and what movement and checking are normal rather than faulty.
  • UKCA certification. What UKCA marking and a Declaration of Performance mean for structural steelwork, and why building control may ask for them.
  • Product maintenance. Keeping steel, stainless, powder coating and glass looking right once it is fitted.
