Architectural Metalwork for Commercial Developments
We're here to help you get exactly what you need, speak to the experts today
Commercial developments carry programme pressures, procurement requirements, and structural demands that require a metalwork contractor who can deliver on specification, on time, and without adding coordination risk to an already complex build. From prefabricated steel stair units in warehouse and distribution environments to plant room guardings, access ladders, and perimeter balustrades across office and business park developments, we design, manufacture and install architectural metalwork for commercial developments across the UK.
Since 2000, Gatehouse Architectural has delivered metalwork solutions for main contractors, commercial developers, and construction teams working across warehousing, distribution centres, office blocks, business parks, and food industry facilities. Our end-to-end service covers in-house CAD/CAM design, UK manufacture at our Kingswinford facility, and nationwide installation managed under a single point of contact, from inception to completion.
CAD / CAM
We produce specific and accurate detail design drawings from the initial idea to the finished product. We will review your project to ensure that you are completely satisfied with your designs prior to manufacture.
Bespoke Metalwork
Our metalwork has been admired by our Clients all over the country. Not only for their practicality, sustainability, and design but also the sheer range of finishes we have available to complement any colour scheme.
Bespoke Design
We can design, manufacture and install anything to suit your specific requirements. Our Metalwork is tailored and engineered to suit Architectural specifications and often state-of- the-art concepts.
Why Commercial Developers and Main Contractors Choose Gatehouse Architectural
Commercial developments demand metalwork that is structurally sound, programme-ready, and specified correctly for the environment it will operate in from day one.
A main contractor working across a commercial development cannot afford a metalwork supplier who introduces delays, produces non-compliant installations, or requires extensive on-site supervision to deliver the finished product. We manufacture in our own facility in Kingswinford, which gives us direct control over production quality, lead times, and delivery scheduling at every stage of the programme. All our structural steelwork carries CE/UKCA marking to EN 1090 Execution Class EXC2 under Certificate of Conformity 0836-CPR-17/F411, and every installation is designed and delivered in full accordance with Building Regulations Part K and Part M. Our CHAS accreditation and Constructionline Gold membership confirm our suitability for both public and private sector commercial procurement without the need for additional pre-qualification.
We work with commercial developers and main contractors to produce metalwork solutions that are cost-effective, compliant, and matched to the specific structural and operational requirements of the facility, whether that is a modular guarding solution for a distribution centre or a fully specified access stair system for a multi-storey commercial building.
Needs and Requirements for Commercial Developments
Commercial developments operate within a framework of structural, safety, and regulatory requirements that must be addressed at the specification stage, not resolved on site.
Structural Compliance and Loading
Commercial and industrial environments require balustrades and barriers designed to withstand a minimum structural load of 1.5kN, with high-traffic areas and public-facing spaces requiring 3.0kN. All balustrade and barrier installations are designed to meet the requirements of Approved Document K, BS 6180, and the Work at Height Regulations where applicable, with structural steelwork fabricated and marked to EN 1090 Execution Class EXC2. We address loading classifications, fixing methods, and substrate compatibility at the CAD/CAM design stage, producing coordinated drawings that integrate with the building structure and the wider construction programme.
Plant Room Guardings and Access Solutions
Plant rooms, mezzanine levels, and elevated working platforms within commercial and industrial buildings require compliant edge guarding and access solutions that meet the requirements of the Work at Height Regulations and Approved Document K. We produce plant room guardings, access ladders, and perimeter balustrades to the correct loading and height specifications for each application, fabricated from mild steel with a primer or polyester powder coated finish as standard. Where stainless steel is specified for hygiene or environmental reasons, as is common in food industry facilities, we carry the full material and finish range to meet that requirement.
Communication and Programme Management
From the moment of our appointment, we coordinate closely with your site team to align our fabrication, delivery, and installation programme with the wider construction schedule. We provide structured updates, coordinated drawings, and installation schedules aligned with the main contractor programme, giving you a single point of accountability for the metalwork scope from drawing to handover. Our in-house manufacturing at Kingswinford gives us direct control over lead times and production scheduling, which means we can respond to programme changes without introducing delays to your critical path.
Prefabricated Steel Stair Units
For commercial and industrial developments working within a Steel Frame System, prefabricated steel stair units offer a significant programme and cost advantage over site-fabricated alternatives. We design and manufacture modular steel stair units for screeding, produced in manageable sections for efficient transport and on-site installation. Our in-house CAD/CAM team coordinates stair unit drawings with SFS manufacturers and installers to confirm that every unit integrates correctly with the building substrate and structural frame before manufacture begins. This removes the risk of on-site dimensional conflicts and keeps your stair core programme on track.
Cost-Effective Solutions for Commercial Programmes
Commercial developments operate within defined budgets and procurement frameworks that require suppliers to deliver value without compromising on structural performance or regulatory compliance. We optimise material selection, fabrication methods, and installation sequencing to produce metalwork solutions that achieve the performance requirements of the specification at a competitive price. Our in-house manufacturing removes unnecessary supply chain margins, and our modular product systems, including our ZuBar balustrade with vertical bar infill panels and our ZuPlex system with perforated or solid plate infill, offer cost-effective solutions for commercial guarding applications without sacrificing finish quality or structural integrity.

FAQs
for Architectural Metalwork for Commercial Developments
Commercial buildings require balustrades and barriers designed to withstand a minimum structural load of 1.5kN under Building Regulations, rising to 3.0kN in high-traffic public areas. All installations must comply with Approved Document K and BS 6180, with structural steelwork fabricated to EN 1090 Execution Class EXC2. We design every commercial installation to the correct loading classification from the initial drawing stage, confirming compliance before manufacture begins.
