OEM Hardware Procurement: 10 Questions to Ask Your Security Hardware Supplier

Choosing the right security hardware supplier is one of the most consequential decisions an OEM door or window manufacturer makes.

The hardware you specify directly affects whether your products meet UK building regulations, pass independent testing, and satisfy the end customers and building control officers who scrutinise every door set and window system you produce.

This guide gives OEM procurement teams a practical framework — 10 direct questions to put to any potential supplier, and how ERA performs against each one.

What should OEM manufacturers look for in a securityhardware supplier?

OEM manufacturers should look for a supplier that offers certified, standards-compliant products, a broad range covering both door and window hardware, reliable lead times, accessible technical support, and a straightforward trade account structure.

ERA online trade portal, ERA Everywhere, was built specifically to serve OEM manufacturers, distributors and installers from a single, dedicated trade platform.

1. Do your products meet UK compliance standards?

This is the first question to ask and the most important.

Your door sets and window systems must meet Building Regulations Part Q and Part B, and the hardware you specify is a core part of that compliance picture.

PAS 24 for enhanced security performance, , TS007 for cylinders, and TS008 for letterplates are the standards your customers and building control will expect to see.

A supplier who cannot provide certified, tested hardware puts your entire product into non-compliance — and the liability sits with you.

How ERA answers this: ERA has a dedicated standards and certification programme that covers PAS 24, Secured by Design (SBD) accreditation, and UKCA/CE-Certifire certification for fire door applications.

ERA's technical and product management team actively navigates compliance standards on behalf of its customers, providing documents (DoP) and certifications that OEM manufacturers can use as part of their own primary fire door assessment reports.

2. How broad is your product range?

For an OEM manufacturer, sourcing from multiple suppliers creates unnecessary complexity — multiple accounts, multiple lead time conversations, and multiple points of failure.

The ideal supplier covers door handles, door locks , cylinders, window locks, hinges and letterplates under one roof.

Range breadth also signals expertise.

A supplier that covers only one product category may not have the same system-level understanding as one that supplies every component within a complete door or window set.

How ERA answers this: Our website is designed as a single destination for OEM hardware procurement.

The range spans window components for casement, sash, and tilt-and-turn systems; door components for entrance, interior, French, and sliding doors; aluminium components; ironmongery; weatherseals; and smart security products.

For OEMs specifying complete door sets or window systems, this breadth means one supplier relationship covers the entire hardware schedule

3. Can you support us with technical specification advice?

Specifying hardware for an OEM door set is not always straightforward.

Backset dimensions, PZ measurements, spindle sizes, cylinder lengths — the variables across a product range are considerable.

An OEM procurement team needs to be confident their supplier has the technical depth to support specification decisions, not just fulfil orders.

Ask whether the supplier has a dedicated technical team, whether they publish specification guides and datasheets, and whether they can advise on compliance implications for specific product combinations.

How ERA answers this: ERA offers dedicated technical support for any queries that you have.

Our team has extensive experience navigating the standards and legislation that govern the UK window and door industry, making ERA a genuine specification partner rather than just a supplier.

4. What are your lead times and how consistent are they?

Production line reliability depends on hardware arriving when expected.

A supplier with excellent products but unpredictable lead times introduces costly disruption into your manufacturing process.

Ask for typical lead times by product category, how they hold up during peak periods, and what the process is if an order is delayed.

How ERA answers this: We operate a dedicated B2B trade ordering platform with online account management, enabling OEM customers to place orders at any time.

Orders are fulfilled from our warehouse, and the platform is purpose-built around the trade buyer's need for speed and reliability.

5. What are your minimum order quantities and payment terms?

Minimum order quantities that are too high tie up capital in stock.

Payment terms that are too short create pressure on working capital.

Understanding the commercial structure of a supplier relationship at the outset avoids problems later.

How ERA answers this: We offers customers the ability to pay by proforma to help with this business model. Free delivery applies on orders over £250, with a £10 charge on smaller orders.

We can clarify minimum order quantities on specific product lines at enquiry stage.

6. Do you offer marketing and merchandising support?

Overlooked in many procurement conversations, this question matters — particularly for OEMs who sell through distributors or trade installers.

If your hardware supplier has strong brand recognition and provides point-of-sale materials, product imagery, or co-branded content, that adds real commercial value to the relationship downstream.

How ERA answers this: We offer a dedicated marketing support for trade customers, including requests for in-store POS, product imagery for use in customer collateral, and content support for websites.

For OEMs whose products reach the end market through distributor networks, this kind of downstream support from a supplier is a meaningful commercial differentiator.

7. How established is the business and how financially stable are they?

Supplier relationships in OEM manufacturing are long-term by nature.

You build specifications around product ranges. You train production teams on fitting processes.

You make commitments to your own customers based on what your supplier can consistently deliver.

Building a core product range around a supplier who then discontinues a key product line — or exits the market — creates serious disruption.

Ask about the supplier's history, ownership structure, and financial stability. Longevity in the market is a meaningful indicator of ongoing reliability.

How ERA answers this: ERA was founded in 1838, giving it over 185 years of history in UK security hardware manufacturing, design and innovation.

ERA operates as part of a wider family of brands in the UK, including Giesse, Reguitti and Zoo Hardware, which are all part of the Quanex Hardware Solutions division of the global Quanex group. So you can be assured that ERA is part of a globally backed supply chain.

This provides OEM customers with access to a diversified, financially stable business rather than a single-product supplier.

8. Can you support multiple door and window system types?

OEM manufacturers rarely produce just one product type.

A business building entrance door sets today may be specifying composite doors, aluminium bifolds and window systems tomorrow.

A supplier that can grow with your product development roadmap — covering uPVC, timber, composite, and aluminium hardware — is significantly more valuable than one with a narrow focus.

How ERA answers this: ERA’s product architecture is built precisely around this need.

Separate product categories for uPVC door components, aluminium door and window components, and timber-appropriate hardware mean OEMs specifying across multiple system types can consolidate their entire hardware procurement with a single supplier.

Fab&Fix, part of the ERA range, provides premium architectural and heritage hardware for OEMs working on higher-specification residential or conservation projects. With up to 13 perfectly matching finishes and over 200 hardware variants, there is a style and finish for every project.

9. How do I place orders and manage my account day to day?

Procurement efficiency matters.

If placing or tracking an order requires a phone call each time, that consumes resource.

Modern trade suppliers should offer a  seamless online ordering experience — a searchable product catalogue, account history, quick reorder functionality, and clear delivery information.

How ERA answers this: ERA Everywhere is a dedicated B2B online ordering platform.

Trade account holders can browse the full product range, use the Quick Shop function for fast reordering and manage their account,— all online and at any time.

The platform is designed around the trade buyer's workflow: easy to navigate, efficient to use, and built to save time on repeat procurement.

10. What does the onboarding process look like?

The ease with which a new supplier relationship gets started often predicts how smooth the ongoing relationship will be.

Ask how long account setup takes, whether you will receive dedicated account support, and whether there is a clear process for getting up and running quickly.

How ERA answers this: Applying for an ERA trade account is a straightforward online process, and only take a few seconds to complete.

Once approved, account holders receive their trading terms and immediate access to the ERA Everywhere online platform.
